A student club spends $78 to buy candy bars and sells them for $3 each to raise money. Construct an equation that models profit or loss for selling a given number of candy bars.​

Respuesta :

Answer: 3x - 78

Step-by-step explanation:

Profit or loss is gotten when the cost is subtracted from the revenue. In this situation, the revenue is given as $78.

Let the total number of candy bars bought be x. Since they are sold at $3 each, all the candy bars will cost 2x.

Profit/Loss = Revenue - Cost

= 3x - 78

If we get a negative value, that's a loss and a positive value denotes profit
