Question

Kalvin sells bottles of water at baseball games. He pays $0.75 per bottle and $3.78 for the ice to keep the water cold. Let b represent the

number of bottles of water he buys and C represent his total cost.
Which equation shows the relationship between his total cost and the number of bottles?
O A. C = b +0.75
O B. C = b +3.78
OC. C = 0.75 +3.78
OD. C = 3.78b+0.75

Answer 1

Multiply the cost per bottle by the number of bottles and add that to the cost of ice.

Answer : C = 0.75b + 3.78
