Vicki bought 3.5 pounds of oranges each pound cost $3.90 which of the following equation represents the total cost C Vicky paid for the oranges and the amount of money she spent?

The equation that represents the total cost C that Vicky paid for the oranges is:

C = 3.90 * 3.5

The equation that represents the total cost C Vicki paid for the oranges is:

C = 3.5 * 3.9

To find the total cost C, we need to multiply the pounds of oranges bought by the cost per pound.

In this case, Vicki bought 3.5 pounds of oranges, and each pound costs $3.90.

So, the equation that represents the total cost C would be:

C = 3.5 * 3.90

Simplifying the equation:

C = $13.65

Therefore, the total cost C that Vicki paid for the oranges is $13.65.
