Final answer:
To find out how much money each of them earn in March, we calculate their commission. Kevin earns 12% commission and Kenneth earns 4 times more commission than Kevin. Adding their monthly salary, Kevin earns $354.60 and Kenneth earns $1013.40 in March.
Step-by-step explanation:
To find out how much money each of them earn in March, we need to calculate their commission.
Kevin earns 12% commission on each product sold. So, the commission he earns on each product is 12% of $610, which is $73.20.
Therefore, Kevin earns a total of $73.20 * 3 = $219.60 in commission.
Kenneth earns 4 times more commission than Kevin, so his total commission is $219.60 * 4 = $878.40.
Adding their monthly salary of $135 each, Kevin earns a total of $219.60 + $135 = $354.60 in March.
And Kenneth earns a total of $878.40 + $135 = $1013.40 in March.
So, the correct answer is C. Kevin earns $354.60 and Kenneth earns $1013.40 in March.
