Solve the Problem $y=40 x+49$ B) $y=-\frac{1}{40} x+\frac{8717}{80}$

Multiple Choice

Solve the problem.

- vendor has learned that, by pricing pretzels at $1.50, sales will reach 109 pretzels per day. Raising the price to $2.50 will cause the sales to fall to 69 pretzels per day. Let y be the number of pretzels the vendor sells at x dollars each. Write a linear equation that models the number of pretzels sold per day (y) when the price is x dollars each.

A) $y=40 x+49$
B) $y=-\frac{1}{40} x+\frac{8717}{80}$
C) $y=-40 x-169$
D) $y=-40 x+169$
