I'm not sure how to do these

2.) The bill at a restaurant came to $136.40. The patrons decided to leave a 15% rip. What was the total of the bill including tip?

3.) Winter coats are marked 70% oof on February 1st. If a coat costs $57.75 on January 31st, how much will it cost on February 1st?

Answer 1

Explanation:

Airfare booked = 208.60

Commission earned = 31.29

Commission rate= 31.29/208.60×100 = 15%

Answer 2

1.) 15%

2.) $156.86

3.) $40.43

Explanation:

1.) 31.29 / 208.6 = .15 * 100 (for percent) = 15%

2.) 136.4 * 1.15 (the original bill plus 15%) = 156.86

3.) 57.75 * .7 = 40.425
