person(1) buys a basket of plural(fruit(1)) on sale for $DOLLARS before tax. The sales tax is SALES_TAX%. What is the total price person(1) pays for the basket of plural(fruit(1))? (Round to the nearest hundredth or cent.) TOTAL_PRICE In order to find the total price, first find the amount of sales tax paid by multiplying the sales tax by the original price of the basket of plural(fruit(1)). SALES_TAX\% \times$DOLLARS =

Percent means "out of one hundred," so SALES_TAX\% is equivalent to \displaystyle\frac{SALES_TAX}{100} which is also equal to SALES_TAX \div 100.

SALES_TAX \div 100 = (SALES_TAX/100).toFixed(2)

Multiply the sales tax you just converted into a decimal by the original price to find the amount of sales tax that must be paid.

SALES_TAX/100 \times $DOLLARS =$((SALES_TAX/100) * DOLLARS).toFixed(2)

Add the sales tax you just found to the original price to find the final price person(1) paid.

$((SALES_TAX/100) * DOLLARS).toFixed(2) +$DOLLARS = $TOTAL_PRICE person(1) needs to pay$TOTAL_PRICE.

roundTo(1, randRange(31,139) / 10 ) randRange(3,200).toFixed(2) roundTo(2, (TAX / 100) * PRICE).toFixed(2)

If the sales tax in your city is TAX%, how much tax would you pay for an item that costs $PRICE before tax? Round to the nearest cent. TOTAL_TAX In order to find the amount of sales tax you would pay, multiply the sales tax by the original price of the item. TAX\% \times$PRICE =

Percent means "out of one hundred," so TAX\% is equivalent to TAX \div 100.

TAX \div 100 = (TAX/100).toFixed(3)

Multiply the sales tax you just converted into a decimal by the original price to find the amount of sales tax that must be paid. Round to the nearest cent.

(TAX/100).toFixed(3) \times $PRICE =$TOTAL_TAX

You would pay $TOTAL_TAX in sales tax. (randRange(8,85)).toFixed(2) randRange(1,11)*5 roundTo(2, PRICE - ( (DISCOUNT/100) * PRICE)).toFixed(2) person(1) bought a new clothing( 1 ) at the store when they were having a DISCOUNT% off sale. If the regular price of the clothing( 1 ) was$PRICE, how much did person(1) pay with the discount?

DISCOUNT_PRICE

First, find the amount of the discount by multiplying the original price of the of the item by the discount.

$PRICE \times DISCOUNT\% = Percent means "out of one hundred," so DISCOUNT\% is equivalent to \displaystyle\frac{DISCOUNT}{100} which is also equal to DISCOUNT \div 100. DISCOUNT \div 100 = (DISCOUNT/100).toFixed(2) Multiply the discount you just converted into a decimal by the original price to find the amount of money saved. (DISCOUNT/100).toFixed(2) \times$PRICE = $((DISCOUNT/100) * PRICE).toFixed(2) Subtract the discount you just found from the original price to get the final price person(1) paid.$PRICE - $(DISCOUNT/100*PRICE).toFixed(2) =$DISCOUNT_PRICE,

person(1) paid $DISCOUNT_PRICE for the clothing(1). randRange(1,11)*5 randRange(6,20) roundTo(2, (DISCOUNT / 100) * PRICE).toFixed(2) The pizza(1) store is having a DISCOUNT% off sale on all of its plural(pizza(1)). If the pizza(1) you want regularly costs$PRICE, how much would you save with the discount?

TOTAL_DISCOUNT

In order to find the amount saved with the discount, multiply the discount by the original price.

DISCOUNT\% \times $PRICE = Percent means "out of one hundred," so DISCOUNT\% is equivalent to \displaystyle\frac{DISCOUNT}{100} which is also equal to DISCOUNT \div 100. DISCOUNT \div 100 = (DISCOUNT/100).toFixed(2) Multiply the discount you just converted into a decimal by the original price to find the amount of money saved. (DISCOUNT/100).toFixed(2) \times$PRICE = $TOTAL_DISCOUNT You would save$TOTAL_DISCOUNT because of the discount.

randRange(20,50) parseFloat(BILL).toFixed(2) randRange(1, 4) * 5 BILL * (TIP_PERCENT / 100) parseFloat(TIP_AMOUNT).toFixed(2) parseFloat(BILL * 0.1).toFixed(2) parseFloat(BILL * 0.05).toFixed(2) BILL + TIP_AMOUNT roundTo(2, parseFloat(TOTAL)).toFixed(2)

person(1) {has {breakfast|lunch|dinner}|eats} at a {restaurant|cafe} and the cost of his(1) meal is $BILL_FORMAT. He(1) would like to leave a TIP_PERCENT% tip. What is his(1) total bill including tip? TOTAL The tip amount is equal to TIP_PERCENT\% \times \$BILL_FORMAT.

We can find the tip by first calculating a 10\% tip and then dividing that number by two. and then multiplying that number by two. and a 5\% tip, and then adding those two numbers together.

To calculate a 10\% tip, move the decimal point in \$BILL_FORMAT one place to the left. 10\% \times \$BILL_FORMAT = \$TIP_TEN_PERCENT To calculate a 5\% tip, divide the 10\% tip amount in half. 5\% \times \$BILL_FORMAT = \$TIP_TEN_PERCENT \div 2 = \$TIP_FIVE_PERCENT.

To calculate a 20\% tip, multiply the 10\% tip amount by two.

20\% \times \$BILL_FORMAT = \$TIP_TEN_PERCENT \times 2 = \$TIP_AMOUNT_FORMAT. Adding the two amounts together gives us \$TIP_TEN_PERCENT + \$TIP_FIVE_PERCENT = \$TIP_AMOUNT_FORMAT.

The cost of the meal plus the amount of the tip will equal the total bill amount.

\$BILL_FORMAT + \$TIP_AMOUNT_FORMAT = \$TOTAL_FORMAT. The total cost of the bill is \$TOTAL_FORMAT.
