Devon earns $35 per hour for a regular 40-hour work week. Sometimes, he works over 40 hours a week and earns "double time" for t

Evgesh-ka [11]

Answer:

Earnings = $1960

Step-by-step explanation:

The question is incomplete; however the missing part of the question asks his total earnings if he worked for 48 hours in a week

First, we need to determine the extra hour worked

Regular Hour = 40

Extra Hour = 48 - 40

Extra Hour = 8

Total Earnings is then calculated as follows:

Earnings = Regular Hours * Regular Charges + Extra Hours * Extra Charges

Earnings = 40 * 35 + 8 * Extra Charges

Since extra charges is twice regular charges, we have:

Earnings = 40 * 35 + 8 * 35 * 2

Earnings = 1400 + 560

Earnings = $1960
