One week,Kristi worked 3 days at a department store for 3 1/2 h each day she was paid 9 dollars per hour.

A.) How many hours did kristi work that week ? Show your thinking.

3 1/2 x 3

3 x 2 + 1 = 7/2 x 3 7/2 + 7 1/2 = 12/21

2 divided by 21 is 10 1/2 hours

B.) How much did kristi earn that week?

( 3 1/2 x 3 ) x 9

10 1/2 + 10 1/2 + 10 1/2 + 10 1/2 +10 1/2 + 10 1/2 + 10 1/2 + 10 1/2 + 10 1/2 = 130 1/2

=130.50 per week.

10.) It takes 3/5 of a tank of gas to get to work and back each day.How much gas is used over 5 work days ? Show your thinking.
