Answer:
around $2769.2
Step-by-step explanation:
Gross earning means the total amount of income earned over a period of time by an individual/household or a company. Simply, how much money does he make per month. We already know that he makes $644 a week. A month has 4.34524 weeks, round up to 4.3. Now, 4.3 multiplied by $644 is $2769.2. Hope this makes sense.
