Vicky bought 3 1/2 pounds of oranges. Each pound cost 3.90. Which of the following equation represents the total cost, c, Vicki paid for the oranges and the amount of money she spent
To find the equation that represents the total cost, we need to multiply the weight of the oranges by the cost per pound.
The weight of the oranges is 3 1/2 pounds, which can also be written as 7/2 pounds.
The cost per pound is $3.90.
Therefore, the equation that represents the total cost c is:
c = (7/2) * 3.90
