Question

While on vacation in Springtown, Darell went out for a dinner that cost $90. If sales tax in Springtown is 10% and Darell left a 20% tip on $90, what was the total cost of his meal?

Answer 1

base cost of dinner is 90

I believe the sales tax is based on the pre-tip amount, so you would add on 10% of 90

then add on 20% of 90 as a tip
