Question

A jacket costs $72.90 before it is marked down 42%. what is its new price, to the nearest cent? a. $30.62 b. $42.28 c. $49.57 d. $51.34 please select the best answer from the choices provided a b c d

Answer 1

Answer: $42.28 (choice b)

===============================================

Reason:

The price goes down 42%, so it keeps the remaining 58%. The two percentages add to 100%

58% of 72.90 = 0.58*72.90 = 42.282 and that rounds to 42.28

Or we could say (1-0.42)*72.90 = 42.282 = 42.28 to have everything in one step.

-------

Another approach:

42% of 72.90 = 0.42*72.90 = 30.618 which rounds to 30.62

You save $30.62 and the final price is 72.90 - 30.62 = 42.28
