The calculation for gross weekly earnings involves summing the pay for regular hours and the pay for overtime hours.

1. Regular Pay: 40 hours × $22.00/hour = $880.00

2. Overtime Rate: $22.00/hour × 1.5 = $33.00/hour

3. Overtime Pay: 5 hours × $33.00/hour = $165.00

4. Gross Earnings: $880.00 (Regular) + $165.00 (Overtime) = $1,045.00

This calculation correctly applies the time-and-a-half premium to the overtime hours worked, as required by most provincial employment standards.

A. This result ($990.00) is calculated by incorrectly paying all 45 hours at the regular rate (45 x $22.00), ignoring the overtime premium.

C. This result ($1,100.00) is calculated by incorrectly paying 50 hours at the regular rate (50 x $22.00), miscounting the total hours.

D. This result ($1,210.00) is calculated by incorrectly paying all 45 hours at the overtime rate of $33.00, which is not how overtime pay works.
