Answer:
The total amount paid to Usan (gross pay) is $416.75
Step-by-step explanation:
15% (tip) per dollar. There are 325 dollars here.
Usan earns $2.15 an hour. There are 20 hours here.
15% times 325 --- 325 * 1.15 (we are adding the tip right away by having the one in front of the .15)
1.15*325 = 373.75
2.15 times 20
2.15*20 = 43
-------------------
373.75 + 43 = 416.75
$416.75
