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?(1 point)
Responses
3.90/3.5 = c; Vicky paid $13.65.
3.90c = 3.5; Vicky paid $0.90.
c/3.5 = 3.90; Vicky paid $13.65.
c/3.90 = 3.5; Vicky paid $1.11.
The correct equation is: c = 3.90 * 3.5; Vicky paid $13.65.
The correct equation that represents the total cost, c, that Vicky paid for the oranges is:
3.90 * 3.5 = c; Vicky paid $13.65.
To find the total cost that Vicky paid for the oranges, we can multiply the weight of the oranges (3 1/2 pounds) by the cost per pound ($3.90).
The correct equation, therefore, is:
c = (3 1/2) * $3.90
Now let's simplify the equation:
c = (7/2) * $3.90
c = (7/2) * $3.90/1
To multiply fractions, multiply the numerators and the denominators separately:
c = (7 * $3.90) / (2 * 1)
c = $27.30 / 2
Now divide $27.30 by 2:
c = $13.65
So Vicky paid $13.65 for the oranges.
Therefore, the correct equation that represents the total cost Vicky paid for the oranges is:
3.90/3.5 = c; Vicky paid $13.65.
