Final answer:
Jquan worked 40 hours this week. He earned $800 last week and needed to earn another $800 this week to reach the two-week total of $1,600. Since he makes $20 per hour, dividing this week's earnings by his hourly wage gives us 40 hours.
Step-by-step explanation:
To calculate the number of hours Jquan worked this week, we first determine his earnings for last week. Since he worked 40 hours and made $20 per hour, his earnings for last week were 40 hours × $20/hour = $800.
His gross pay for the two-week period is $1,600. To find out how much he earned this week, we subtract last week's earnings from the total two-week earnings: $1,600 - $800 = $800.
Now, to calculate the number of hours he worked this week, we take the total earnings for this week and divide by his hourly wage: $800 ÷ $20/hour = 40 hours.
Therefore, Jquan worked 40 hours this week to achieve a gross pay of $1,600 for the two-week period.
