Question

A. c/3.5 = 3.90; Vicky paid $13.65
B. c/3.90 = 3.5; Vicky paid $1.11
C. 3.90/3.5 = C; Vicky paid $13.65
D. 3.90c=3.5; Vicky paid $0.90

Answer 1

The correct equation to represent the total cost, c, that Vicky paid for the oranges and the amount of money she spent would be:

D. 3.90c = 3.5

This equation represents that Vicky paid a certain amount per pound (3.90) and that amount is multiplied by the number of pounds (3.5) to get the total cost.

The incorrect statements in the other options are:
A. The equation is dividing the total cost (c) by the number of pounds (3.5), which is not correct.
B. The equation is dividing the total cost (c) by the cost per pound (3.90), which is not correct.
C. The equation is dividing the cost per pound (3.90) by the number of pounds (3.5), which is not correct.
