Each day, the shampoo bottle goes down 1/2 an ounce because 1 - (1/2) = 1/2

After four days the shampoo bottle is 2 ounces lower because 4 x (1/2) = <<4*(1/2)=2>>2

After four days, the shampoo bottle has 8 ounces of liquid left because 10 -2 = <<10-2=8>>8

After four days the shampoo bottle has 2 ounces of hot sauce 4 x (1/2) = <<4*(1/2)=2>>2

The proportion of hot sauce in the bottle is .25 because 2 / 8 = <<2/8=.25>>.25

The percentage of hot sauce is 25% because .25 x 100 = <<.25*100=25>>25
