Question

isabel pays a total of $50.00 for every 18 shirts she has dry-cleaned. which graph models a relationship with the same unit rate where x shirts are dry cleaned for a total of y dollars.
a
b
c
d

Explanation:

Step1: Calculate unit rate

First, find the cost per shirt. The unit rate is $\frac{50}{18} \approx 2.78$ dollars per shirt.

Step2: Test x=9 for unit rate

For 9 shirts (half of 18), cost should be $\frac{50}{2}=25$ dollars.

Step3: Match to graph points

Check which graph has the point (9, 25). Graph A has (9, 25), while others have higher y-values for x<10, which don't match the unit rate.

Answer:

A. The first graph (with points like (9, 25) following the unit rate of $\frac{50}{18}$ dollars per shirt)
