Answer:

5 cars must be sold for profits to be equal.

Explanation:

Two companies offer Jane a sales position. Company A pays $3,000 per month plus $250 per car sold. Company B pays $2,500 per month plus $350 per car sold. Which equation could be used to determine the number of cars sold in a month, x, that would result in the same total income from each company?

Company a profit: 3,000 + 250x

Company b profit: 2,500 + 350x

They ask for x when:

company a profit = company b profit

3,000 + 250x = 2,500 + 350x

subtract 2,500 from both sides:

3,000 + 250x - 2,500 = 2,500 + 350x - 2,500

500 + 250x = 350x

subtract 250x from both sides:

500 + 250x -250x = 350x - 250x

500 = 100x

divide both sides by 100:

500/100 = 100x/100

x = 5

5 cars must be sold

check: when x = 5

3,000 + 250x = 2,500 + 350x

3,000 + 250(5) = 2,500 + 350(5)

3,000 + 1,250 = 2,500 + 1,750

4,250 = 4,250
