The bar graph shows the work done at a small automotive repair shop during a recent week. how many more customers had oil changes than tune-ups?

Hello!

I believe that 5 more customers had Oil Changes than Tune-Ups. You can find this answer by looking at how many people are represented on the graph. For Oil Changes, there are 11 people represented while for Tune-Ups, there are 6 people represented, so you need to subtract 6 from 11 to get 5 people as your answer

I hope this helps!
