An employee makes an hourly rate plus any tips they earn. This tip employee made a total of $400 by working 28 hours last week. If $253 of their total earnings was their tips, what is their hourly rate of pay?

Rate = $X per hour.

Pay = 28X + 253 = 400
28x = 400 - 253 = 147
X = $5.25 per hour.

Erica sells magazine subscriptions and makes a flat rate of $5.35 for each subscription she sells. If Erica made $42.80 on Monday, $64.20 on Tuesday and $74.90 on Wednesday, how many subscriptions did she sell in the three days?

To find the hourly rate of pay, we need to first subtract the tip amount from the total earnings to determine the base pay. Then we can divide the base pay by the number of hours worked to calculate the hourly rate.

Step 1: Subtract the tip amount from the total earnings.
Total earnings - Tips = Base pay
$400 - $253 = $147

Step 2: Divide the base pay by the number of hours worked.
Base pay / Hours worked = Hourly rate
$147 / 28 = $5.25

Therefore, the employee's hourly rate of pay is $5.25.
