Pauline spent $7.50 every day for 3 days. which expression is the best choice to her determine the total amount of money she spent?

(7.50)(−3) = −22.50; she spent $22.50
(−7.50)(3) = −22.50; she spent $22.50
(−7.50)(−3) = 22.50; she spent $22.50
(7.50)(3) = 22.50; she spent $22.50

The correct option is 2.

Step-by-step explanation:

It is given that Pauline spent $7.50 every day for 3 days.

Amount spent on each day = $7.50

Number of days = 3

Spent amount and expenditure are always negative.

Total amount of money she spent is

On simplification we get

She spent $22.50 and required expression is (−7.50)(3) = −22.50. Therefore the correct option is 2.
