After the journalism club sold 60 magazines, it had $220 in profit. After it sold a total of 100 magazines, it had a total of $420 in profit. Which equation models the total profit, y, based on the number of magazines sold, x?

A. y - 220 = 2 (x - 60)

B. y + 220 = 5 (x + 60)

C. y + 220 = 2 (x + 60)

D. y - 220 = 5 (x - 60)

For this item, we let x be the number of magazines sold and y be the profit as instructed. Based from the data given, the system of linear equation that would best depict the given scenario is,

220 = 60x + b

420 = 100x + b

The values of x and b in the equation are 5 and - 80.

y = 5x - 80

From the given choices, the answer should be the last choice.
