Vicky bought 3 1/2 pounds of oranges. Each pound costs $3.90. Which of the following equations represents the total cost, c, Vicky paid for the oranges and the amount of money she spent?
A: c/3.90 = 3.5; Vicky paid $1.11.
B: c/3.5 = 3.90; Vicky paid $13.65
C: 3.90/3.5 = c; Vicky paid $13.65
D: 3.90c = 3.5; Vicky paid $0.90
The equation that represents the total cost, c, Vicky paid for the oranges and the amount of money she spent is option C: 3.90/3.5 = c; Vicky paid $13.65.
To solve this problem, we need to multiply the weight of the oranges by the cost per pound to find the total cost.
First, we find the cost per pound by dividing the total cost by the weight of the oranges: 3.90 / 1 = $3.90.
Next, we multiply the cost per pound by the weight of the oranges: 3.90 * 3.5 = $13.65.
So, the correct equation representing the total cost, c, Vicky paid for the oranges is B: c/3.5 = 3.90; Vicky paid $13.65.
The correct equation to represent the total cost, c, Vicky paid for the oranges is:
c = 3.50 * 3.90
So, the correct option is D: 3.90c = 3.5; Vicky paid $0.90.
