3.903.5=c
; Vicky paid $13.65.
Start Fraction 3.90 over 3.5 End Fraction equals c ; Vicky paid $13.65.

3.90c=3.5
; Vicky paid $0.90.
3.90 c equals 3.5 ; Vicky paid $0.90.

c3.5=3.90
; Vicky paid $13.65.
Start Fraction c over 3.5 End Fraction equals 3.90 ; Vicky paid $13.65.

c/3.90=3.5
; Vicky paid $1.11.

Answer 1

To determine the total cost \( c \) that Vicky paid for the 3.5 pounds of oranges, we can use the equation that represents the relationship between the cost per pound and the total cost:

\[ c = \text{(cost per pound)} \times \text{(number of pounds)} \]

In this case:

\[ c = 3.90 \times 3.5 \]

Now, calculating the total cost:

\[ c = 3.90 \times 3.5 = 13.65 \]

So, the correct equation that represents the total cost is:

\[ c = 3.90 \times 3.5 \]

Thus, the appropriate response is:

\[ 3.90 \times 3.5 = c; \text{ Vicky paid } $13.65. \]
