Question

Jill works as a waitress at the local diner where she earns an hourly wage of $4.00 per hour and a standard tip rate of 15% of the cost of the orders she serves. If she worked four 8-hour shifts this week and averaged $40 in orders per hour, how much did Jill earn this week?

A. 280
B. 300
C. 320
D. 350
E. 400

Answer 1

The amount she earned during the week is $320

Using the parameters given for our Calculation;

• tip rate = 15% of cost of orders
• cost of orders = 40
• Work hour = 4 - 8hour shift
• Earning per hour = $4

The total number of hours worked = (4 × 8) = 32 hours

Total earnings from.hours worked = (32 × 4) = $128

The percentage earning from tip = (40 × 0.15) = 6

Tip earned after 32 hours = 6 × 32 = $192

Total earning = 128 + 192 = $320

Hence, her week's earning is $320
