One yard of ribbon cost $4.50. Olivia buys 2 1/2 yards of ribbon. She gives the clerk four $5.00 bills. How much change does Olivia get back?

Jerry set a goal to run 10 kilometers during the school week. He ran 3.42 miles on Monday and 2.7 miles on Tuesday. How many miles does Jerry still need to run to reach his goal?
*hint: 1 kilometer = 0.62 miles*
1 km = 0.62 miles
10 km = 10 x 0.62 miles
10 km = 6.2 miles
3.42 miles + 2.7 miles = 6.12 miles
6.20 miles - 6.12 miles = 0.8 miles
Jerry needs to run 0.8 more miles to reach his goal
