After the booster club sold 40 hotdogs at a football game, it had $90 in profit. after the next game, it had sold a total of 80 hotdogs and had a total of $210 in profit. which equation models the total profit, y, based on the number of hotdogs sold, x?

A

Step-by-step explanation:

We can use (hotdogs sold(x), profit(y)) as a coordinate pair to come up with 2 points and then use the formula for equation of a line to figure this out.

Thus, the 2 coordinate points are:

(40, 90) and (80, 210)

Finding the slope, m, as:

Where x_1 = 40, y_1=90  AND  x_2 = 80 and y_2 = 210

We plug and find m:

Equation of line is  

we can plug in the values we know:

A is the correct answer.
