Question

Billie Sue's BBQ had their grand opening this year. The first month they did not turn a profit. However, each month thereafter, they have had steady profits of $1,900 per month. If x represents the number of months they have profited, which of the following equations represents the amount of profits after x months?
A. y = 1,900x B. y = x + 1,900 C. y = 1,900 - x D. y = 1,900x + x

Answer 1

Since each month profit is $1,900, it should be multiplied by 1900 as the time goes by. For example, one month profit is 1900, two month profits are 2*1900, three months profits are 3*1900, and so on...

So, it's Y (the amount of profits after X months) = 1900*X

Answer 2

Answer:

A. y = 1,900x
