Solve. Assume the exercise describes a linear relationship.A vendor has learned that, by pricing hot dogs at $1.25, sales will reach 131 hot dogs per day. Raising the price to $2.00 will cause the sales to fall to 101 hot dogs per day. Let y be the number of hot dogs the vendor sells at x dollars each. Write a linear equation that models the number of hot dogs sold per day when the price is x dollars each.
A. y = 40x + 81
B. y = -40x - 181
C. y = -40x + 181
D. y = -
