c3.90=3.5; Vicky paid $1.11.
Start Fraction c over 3.90 End Fraction equals 3.5 ; Vicky paid $1.11.
c3.5=3.90; Vicky paid $13.65.
Start Fraction c over 3.5 End Fraction equals 3.90 ; Vicky paid $13.65.
3.90c=3.5; Vicky paid $0.90.
3.90 c equals 3.5 ; Vicky paid $0.90.
3.903.5=c; Vicky paid $13.65.
The correct equation is: c = 3.90 * 3.5
The equation that represents the total cost, c, Vicky paid for the oranges and the amount of money she spent is:
c = 3.90 * 3.5
Therefore, the correct option is:
3.90c = 3.5; Vicky paid $13.65.
To find the total cost, c, that Vicky paid for the oranges, we need to multiply the weight of the oranges (3 1/2 pounds) by the cost per pound ($3.90).
First, we convert the mixed fraction 3 1/2 to an improper fraction: 3 1/2 = 7/2.
Then, we can multiply the weight (7/2) by the cost per pound ($3.90):
c = (7/2) * $3.90
To simplify the equation, we can multiply the numerator of the fraction by the cost per pound:
c = (7 * $3.90) / 2
c = $27.30 / 2
c = $13.65
Therefore, Vicky paid $13.65 for the oranges.
The equation that represents the total cost, c, and the amount of money Vicky spent is:
c = 3.5 * 3.90
Simplifying it further, we get:
c = 13.65
Hence, the correct equation is:
c = 3.5 * 3.90 ; Vicky paid $13.65.
