Answer:
-75 cents
Step-by-step explanation:
Pilar decreased the amount she spent at the grocery store by 15 cents for each reusable bag she used.
Therefore, the amount she spent changed by -15 cents for each reusable bag she used.
Multiply the number of bags by -15 cents per bag to find the total change to the amount Pilar spent.
5 bags × (-15 cents per bag) = -(5 bags × 15 cents per bag)
= -75 cents
Therefore, the amount Pilar spent at the grocery store changed by -75 cents because she used 5 reusable bags.
