Answer:
$750
Step-by-step explanation:
Given the following:
i. first job pays $880 per week
ii. second job pays $790 per week
amount first job is paying more= ($880 - $790) = $90
Hence,12% should equate $90 if Thomas wants to make the second job pay him as much as the first job
Therefore, 12% of X = $90
12÷100 * X = $90
X = 90 * 100 ÷ 12
X= 9000 ÷ 12
X = $750
Hence, Thomas has to make a sale of $750 to earn a 12% comission of $90
