A. m + 0.15m
B. m - 0.15m
C. 0.15m
D. m * 0.15

Answer 1

The expression for the total amount Sally paid for the pizza and the 15% tip is m + 0.15m, which represents the initial bill (m) plus the tip (0.15m).

Step-by-step explanation:

To write an expression for the total amount of money Sally paid for the pizza and tip, we need to calculate both the initial bill and the additional tip amount. If the bill for the pizza was m dollars, and Sally tipped the deliverer 15% of the bill, we first convert 15% to a decimal by dividing 15 by 100, which gives us 0.15. We then multiply the bill amount by this decimal to find the tip amount.

m dollars for the pizza + 0.15 × m dollars tip = m + 0.15m (The total amount paid including tip)

Therefore, the expression representing the total amount Sally paid for the pizza and tip is m + 0.15m.
