Answer:
$8.46 for tip. The total you paid was $64.86 plus tip.
Explanation:
1. Why? First, you need to know the percentage to whole to get to your part. PERCENTAGE: 15% WHOLE: $56.40. (A percent is the percentage of a whole, which is the total.) You need to multiply to get the part.
15% times $56.40
2. How to multiply the percentage to whole.
Put the 15 into a fraction. 15/100, then put the fraction into a demail. (15/100=0.15) Now, multiply.
0.15 x 56.40
(You can add your tip and the bill to get the total of money you spend)
