Question

A babysitter charges 25% more than her normal hourly rate on Saturday night. Her normal hourly rate is $12.50.

Which expression represents how much the babysitter charges on Saturday night?

Answer 1

if the babysitter hourly rate is 12.50 on a regular day basis, lets find out first how much is 25% of 12.50
12.50/4= 3.125
so on a Saturday night she will charge 12.50+3.125= 15.625, which is aprox.
15.63 dollars/hour

Answer 2

I am positive the answer is $12.50 * 5/4.
