If he babysits for 2 hours at $7 per hour, he will earn 2*7 = $<<2*7=14>>14

This week he will earn $5 allowance, $10 mowing the lawn and $14 from babysitting for a total of 5+10+14 = $<<5+10+14=29>>29

If we add the $29 he will earn to his $65 savings, he will have a total of 29 + 65 = $<<29+65=94>>94

The bike costs $100 and he will have $94 leaving $100-$94 = $<<100-94=6>>6 more that he will need to earn

Zach is saving his money to buy a brand new bike that costs $100.  His weekly allowance is $5.  His parent will pay him an extra $10 to mow the lawn.  His neighbor will pay him $7 per hour to babysit their son.  He has already saved up $65.  He'll receive his allowance on Friday and he's planning on babysitting for 2 hours this Saturday after he mows the lawn.  How much more money does Zach need to earn before he can buy the bike?
