Multiple Choice

Solve.
hat
-A vendor has learned that, by pricing hot dogs at $\$ 1.50$ , sales will reach 85 hot dogs per day. Raising the price to $\$ 2.25$ will cause the sales to fall to 49 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) \(y = - \frac { 1 } { 48 } x + \frac { 2719 } { 32 }\)
• B) \(y = - 48 x - 157\)
• C) \(y = - 48 x + 157\)
• D) \(y = 48 x + 13\)
