Question

The price of a notebook has gone up to $3.70 today. Yesterday it was $3.20 , what is the percent increase?

Answer 1

percent of increase (or decrease) = change in price/original price

In this problem, change in price is $3.70 - $3.20 = .50

so percent increase is .50/3.20 = 15.625%

Answer 2

round to the nearest tenth?

Answer 3

you can change .50/3.20 by using your calculator and getting .15625

Change .15625 to a percent by moving the decimal point 2 places to the right, you get 15.625%.

Answer 4

Answer 5

Answer 6

Yes, 15.6%.
