Chloe's family ate dinner at a restaurant and the bill was $86. If sales tax was 7.5% and they tipped 20% of the original bill, what was the total amount that Chloe's family paid for dinner?
If we find what the 7.5% is (6.45) and find what the 20% is (17.20) and add them all together, we get 109.65. If I'm wrong, please correct me. I still have some doubts.
