Answer:
12%
Explanation:
I just guess some possible percents of tip to find the answer. When multiplying percents you must 1st turn it onto a decimal. So 15% = 0.15 or 20% = 0.20
$24.83 × 0.20 = 4.966 NO
$24.83 × 0.15 = 3.724 NO
$24.83 × 0.10 = 2.483 NO
$24.83 × 0.12 = 2.979 YES
round 2.979 to 2.98 so that means tip was 12%
