Question

Two teams are selling candy bars to raise money. Team A has $165 saved and they are selling each candy bar for $2. Team B has $74 saved and is selling each candy bar for $3. How many candy bars do they both need to sell to have the same amount of money?

Answer 1

Answer: Each have to sell 91 candy bars to have the same amount of money.

Explanation: Suppose x represents the amount of candy bars.

Team A already have $165 and they are selling each candy bar for $2. The mathematical equation that represents the amount of money they have is

A: 165 + 2x

Team B initially has $74 and will sell each candy bar for $3. Then, the mathematical equation representing their amount of money is

B: 74 + 3x

So, to have the same amount of money:

165 + 2x = 74 + 3x

x = 165 - 74

x = 91

Teams A and B will have the same amount of money when each of them sell 91 candy bars.
