Pauline spent $7.50 every day for 3 days. Which expression is the best choice to help her determine the total amount of money she spent?
A. (7.50) × (−3) = −22.50; She spent $22.50.
B.(−7.50) × (3) = −22.50; She spent $22.50.
C. (−7.50) × (−3) = 22.50; She spent $22.50.
D. (7.50) × (3) = 22.50; She spent $22.50.
Since Pauline spent $7.50 for 3 days, all you have to do is multiply 7.50 by 3 to get 22.50. Your answer would be D.(7.50) × (3) = 22.50; She spent $22.50.
