The graph that shows the unit rate for the given situation is; D; Graph D
We are given;
Number of hours Sara worked a week; x = 40 hours
Amount Sara earned a week; y = $660
Now, this means that the rate of amount earned per hour is; 660/40 = $16.5 per hour
Now, the graph that will be correct must have it's, change in y to change in x ratio as 16.5.
The only graph that has a slope which is change y to change in x ratio as 16.5 is graph D because we see that the ratio is approximately $16.5 per 1 hour.
