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 .

Question

3.90c = 3.5 Vicky 0.90

3.90/3.5 = c; Vicky paid 13.65

C/3.90 = 3.5; Vicky paid 1.11
C/3.5=3.90 Vicky paid 13.65

Answer 1

To find the total cost \( c \) for the oranges that Vicky bought, we can use the following relationship:

\[ \text{Total Cost} = \text{Cost per pound} \times \text{Number of pounds} \]

In this case:

• The cost per pound is \( 3.90 \)
• The number of pounds is \( 3.5 \)

So the equation representing the total cost \( c \) would be:

\[ c = 3.90 \times 3.5 \]

Calculating that gives:

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

Out of the provided options, the correct representation of the total cost would be in the form of:

\[ C / 3.90 = 3.5 \] which leads to

\[ c = 3.90 \times 3.5 \]

The amount paid is confirmed as \( 13.65 \), which matches the calculation.

Thus, the option that represents the total cost and the amount of money she spent correctly is:

C/3.90 = 3.5; Vicky paid 13.65.
