Your brother Liam is having his graduation this summer and he has asked you to help him select a photographer for the big event. You called around and found that Penelope the Photographer charges a $100.00 setup fee, plus $12.25 per hour. You discover Jessie's Jumpin' Photos has a $108.00 setup fee, plus $10.00 per hour.
You plan to have the photographer take pictures for 4 hours. Liam claims that Penelope the Photographer will be the better deal. Is Liam correct? Support your reasoning. Liam is correct/incorrect, because…
Liam is incorrect because Penelope will charge $149 and Jessie will only charge $148.
