Answer:
$43.38
Step-by-step explanation:
Step 1 : find 20% of price
To do this, all you have to do is multiply the decimal version of the percent (20% --> 0.20) by your full price
36.15 × 0.20 = 7.23
Step 2 : add tip to total cost
now we get that tip we got in the first step and add it to 36.15
36.15 + 7.23 = $43.38
