Rachel budgeted $76.50 for school clothes. This is 0.45 of her total budget. How much does Rachel have in her total budget?

• 0.45b = 76.50; $170.00

• 76.50b = 0.45; $0.05

• 0.45b = 76.50; $190.00

• 0.55b = 76.50; $139.10

Overnight, the temperature dropped 1.3 degrees every hour. How many hours did it take the temperature to drop 7.8 degrees?

• -7.8h = -1.3; h = 0.17 hours

• -7.8h = 1.3; h = 6 hours

• -1.3h = -7.8; h = 10.14 hours

• -1.3h = -7.8; h = 6 hours

Evaluate the expression for s.

• s = 7/27

• s = 5/7

• s = 3/7

• s = -1/6
