Selena and her friends went out to dinner. The bill came to $56.25. If the the tax rate is 7.5 percent and they left a 15 percent tip. How much money did they spend at the restaurant ?
When the bill is presented to me, I see the cost of the meal plus the tax.
56.25 * 1.075 = $60.47
Then I'd figure the tip on that amount.
60.47 * 0.15 = $9.07
60.47 + 9.07 = 69.54
