Question

Cheese sticks that were previously priced at "5 for $1" are now "4 for $1". What is the percent change?

Answer 1

5%

Explanation:

Previously 1 was priced = $ 1/5. and now 1 is priced = $1/4.

So change of price for 1 = `1/4 - 1/5 = (5-4)/20 = 1/20`

Hence change of percent = 1/20 x 100 = 5
