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)
c = 3.5 * 3.90
To find the total cost, we can multiply the weight of the oranges by the cost per pound.
Given that Vicky bought 3 1/2 pounds of oranges, we first need to convert the mixed number to an improper fraction.
3 1/2 = (2*3 + 1)/2 = 7/2
Now, we can calculate the total cost by multiplying the weight (in pounds) by the cost per pound.
Total cost (c) = (7/2) * $3.90
This can be represented by the equation:
c = (7/2) * $3.90
To find the total cost, c, that Vicky paid for the oranges, we need to multiply the number of pounds by the cost per pound.
First, we convert the mixed number, 3 1/2 pounds, to an improper fraction.
3 1/2 pounds = 7/2 pounds
Next, we multiply the number of pounds by the cost per pound.
Total cost, c = (7/2 pounds) * ($3.90/pound)
We can simplify this equation by canceling the common factors.
Total cost, c = 7 * $3.90 / 2
Multiplying the numerator and simplifying, we get:
Total cost, c = $27.30 / 2
Finally, dividing $27.30 by 2, we find:
Total cost, c = $13.65
Therefore, the equation that represents the total cost, c, Vicky paid for the oranges is:
c = $13.65
