(1) 107$
(2) 107.30$
(3) 107.40$
(4) 107.35$
Solution:
Brianna spends $8.95 on a car wash every month. There are 12 months in a year. Multiply to find how much she spent on car washes last year.
First, multiply a related set of whole numbers. Find 895*12.
895*12 = 10740
Now, count the number of decimal places in the factors. There are two decimal places in 8.95, so move the decimal point two places to the left in your answer.
10740 → 107.40
Brianna spent $107.40 on car washes last year.
