Solve the problem.A vendor has learned that, by pricing pretzels at $1.00, sales will reach 112 pretzels per day. Raising the price to $2.00 will cause the sales to fall to 68 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 when the price is x dollars each.
A. y = -44x - 156
B. y = - 
x + 
C. y = 44x + 68
D. y = -44x + 156
