question 252

Multiple Choice

Solve.
-A vendor has learned that, by pricing pretzels at $\$ 1.75$ , sales will reach 56 pretzels per day. Raising the price to $\$ 2.25$ will cause the sales to fall to 34 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 $\mathrm { x }$ dollars each.

• A) \(y = - 44 x + 133\)
• B) \(y = - \frac { 1 } { 44 } x + \frac { 9849 } { 176 }\)
• C) \(y = 44 x - 21\)
• D) \(y = - 44 x - 133\)
