Answer:
a) If Sales = $6412454, then Gross Pay = $471315.369.
If Sales = $412454, then Gross Pay = $30315.369.
b) If Sales = $316250, then Gross Pay = $23244.375.
Step-by-step explanation:
This is a simple question. Madelyn earns a commission plus a bonus from her job. The commission is 7% of sales and the bonus is 5% of the commission. Therefore:
a) If her sales are $6412454, then her gross pay will include:
Gross Pay = $6412454 * 7% + ($6412454 * 7%) * 5%.
Gross Pay = $448871.78 + $22443.589 .
Gross Pay = $471315.369.
I assume there is a typo in the question, so just in case, I will also calculate the gross pay for her sales equaling $412454.
Gross Pay = $412454 * 7% + ($412454 * 7%) * 5%.
Gross Pay = $28871.78 + $1443.589 .
Gross Pay = $30315.369.
b) If her sales are $316250, then her gross pay will include:
Gross Pay = $316250 * 7% + ($316250 * 7%) * 5%.
Gross Pay = $22137.5 + $1106.875 .
Gross Pay = $23244.375.
To summarize:
If Sales = $6412454, then Gross Pay = $471315.369!!!
If Sales = $412454, then Gross Pay = $30315.369!!!
If Sales = $316250, then Gross Pay = $23244.375!!!
