tommy took one of his friends out to dinner. the dinner cost $100 and he paid 3% sales tax. if tommy left an 18% tip on the $100, how much in total did he pay?
Answer
Explanation:
Step1: Calculate sales - tax amount
The sales - tax rate is 3% of $100. So the sales - tax amount is $100\times0.03 = 3$.
Step2: Calculate tip amount
The tip rate is 18% of $100. So the tip amount is $100\times0.18=18$.
Step3: Calculate total amount
The cost of dinner is $100, the sales - tax is $3 and the tip is $18. The total amount is $100 + 3+18=121$.
Answer:
121
