A pound of candy costs x dollars. One of the friends bought 5lb and the second friend bought 7lb candies for the party. How much money did they spend together

The total money spent equals $12x.

Step-by-step explanation:

First friend spent $5x, representing 5Ib of candies at a price of $x each.

Second friend spent $7x, representing 7Ib of candies at a price of $x each.

Total pounds of candies bought = 5 + 7 = 12

Therefore, total cost of candies bought = 12 multiplied by x, which = $12x

The total quantity of candies bought multiplied by the price per pound gives the total money spent altogether.

Total cost C = 12x dollars

Step-by-step explanation:

Given;

A pound of candy costs x dollars.

x represent the price of one candy

One of the friends bought 5lb;

Cost C1 = 5lb * x dollars/lb

Cost C1 = 5x dollars

The second friend bought 7lb candies for the party;

Cost C2 = 7lb * dollars/lb

Cost C2 = 7x dollars

The total cost is the sum of the two costs;

C = C1 + C2

C = 5x + 7x

Total cost C = 12x dollars
