The Williams family has a coupon for 10% off their dinner. Their bill comes to $82.50 and they wish to tip 15%, what will they pay in total?

PLLLEEAAS WILL GIVE BRAINILEST!!!

The Williams family will pay $94.88 in total

Step-by-step explanation:

Well since the family is tipping 15% to the 10% reduced order, that comes to a 5% increase of the bill right? Well yes, but actaully no. This seems like the problem already subtracted the 10% out meaning that you have to put the 15% in. Now how you multiply percentages, you move the imaginary decimal that is directly after the 5, so for example 15.00. You move that to the left 2 times making it .15 to which you multiply 82.50 times .15 and you end up getting 12.375 but there's no thousandth of a dollar, so you round up to the nearest hundreth which would make it 12.38. This isn't the final answer though, you have to add the 12.38 to the 82.50 and get 94.88.
