Question

3. Silver’s Cleaners decided to raise the price of dry cleaning sports coat from $4 to $5. The same percentage increase was applied to dry cleaning a jacket. The old cost of dry cleaning a jacket was $10. What is the new cost of dry cleaning a jacket?

Answer 1

Answer:

$4 is increased to $5

$1 is increased

1/4 × 100 = 25%

Let the price increased be x

x/10 × 100 = 25%

10x = 25/100

x = 2.5

Therefore new price = 10 + 2.5 = 12.5

New price is $12.5
