3.90/3.5=c; Vicky paid $13.65.

c/3.90=3.5; Vicky paid $1.11.

3.90c=3.5; Vicky paid $0.90.

c/3.5=3.90; Vicky paid $13.65.

1 answer

To find the total cost \( c \) that Vicky paid for 3 1/2 pounds of oranges at a cost of $3.90 per pound, we can set up the equation as follows:

The total cost can be calculated by multiplying the weight in pounds by the cost per pound:

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

In this case:

\[ c = 3.90 \times 3.5 \]

This means that the correct representation of the total cost equation is:

\[ c = 3.90 \times 3.5 \]

This can be rearranged to fit one of the provided options if we express it differently, but among the given options, none of them correctly represent the straightforward multiplication to find the total cost.

However, if we were to solve for \( c \) from the equation \( c / 3.5 = 3.90 \), which can be rearranged to \( c = 3.90 \times 3.5 \), this gives:

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

Thus, the correct option to choose from the provided answers is:

c/3.5=3.90; Vicky paid $13.65.
