$14.75 x 7.5 hours = $110.625
Because cents only go to the hundredths place, she would earn $110.63.

Ashley multiplied
13.2 x 9.9 and got a product of 13.068. Is her answer reasonable? How do you know?
This answer is not reasonable. 13.2 is about 13 and 9.9 is about 10.
13 x 10 = 130 so the answer
is 130.68 and NOT 13.068.
