Solve the problem.A vendor has learned that, by pricing hot dogs at $1.25, sales will reach 127 hot dogs per day. Raising the price to $2.25 will cause the sales to fall to 75 hot dogs per day. The number of hot dogs, N, is a linear function of the price, x. Write a linear function that models the number of hot dogs sold per day when the price is x dollars each.

A. N(x) = 52x + 62
B. N(x) = -52x + 192
C. N(x) = -52x - 192
D. N(x) = - x +
