Question

if Cassette tapes are currently $12 each and are expected to increase in price by 25% what will the new price be?

Answer 1

25/100=x/12

100x=300

100x/100=300/100

x=3

12+3=15

3 is 25 percent of 12 so the new price is $15

Answer 2

Adding 25% is multiplying by 1.25:

$12 × (1 + 25/100) = 12(1.25) = $15

Answer: $15
