Answer:
65.62
Step-by-step explanation:
Given:
After eating a meal at a restaurant, we decided to tip 25%, building a grand total of $87.50.
To find:
Price before tip
Solution:
87.50 × 25% = 21.875
~Round~: 21.875 to 21.88
87.50 - 21 .88 = 65.62
Thus the price before the tip is 65.62
Check Answer:
<em>Formula: Higher number - Lower number ÷ original number × 100</em>
<em>Solve: </em>
<em>87.50 - 65.62 = 21.88</em>
<em>21.88 ÷ 87.50=0.25005714285</em>
<em>0.25005714285 × 100 = 25.0057142857</em>
<em>Round - 25%</em>
