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.

c3.90=3.5
; Vicky paid $1.11.

To find the total cost \( c \) that Vicky paid for the 3 1/2 pounds of oranges at a cost of $3.90 per pound, you can represent this situation with the following equation:

\[ c = 3.90 \times 3.5 \]

Calculating this gives:

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

So, the correct way to represent the total cost is:

\[ c = 3.90 \cdot 3.5 \]

Therefore, the equation representing the total cost, \( c \), is:

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

In your provided options, the correct representation would likely be:

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

However, that isn't exactly correct because \( c \) should be multiplied by 3.5, but it's the closest alignment with the total cost representation.

So, the format matching your options isn't ideal, but remember \( c = 3.90 \times 3.5 \) is the key equation leading to a total cost of $13.65.
