My question is: Bob and Kate went to a restaurant for dinner. After they were done eating the waitress gave a $30 bill to Bob and a $25 bill to Kate, but told them they were eligible for special discounts; 5% for Bob, 2% for Kate. Considering the discounts, how much do they have to pay in total? Your thoughts:

5% of $30 is (5 / 100) * 30 = $1.5. The dollar amount of Bob's discount is $1.5 so he will pay $30 - $1.5 = $28.5. 2% of $25 is (2 / 100) * $25 = $0.5. The dollar amount of Kate's discount is $0.5 so she will pay $25 - $0.5 = $24.5. Altogether they will pay $28.5 + $24.5 = $53. The final answer: 53.
