###Human: 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?, ### Assistant: 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 
 So the answer is :  53
