Answer:
First, we need to calculate Danielle's commission on the merchandise she sold:
Commission = 7.25% of $4,100 = 0.0725 x $4,100 = $296.25
Next, we need to calculate her total earnings for the week:
Total earnings = Base salary + Commission
Total earnings = $725 + $296.25
Total earnings = $1,021.25
Therefore, Danielle earned $1,021.25 last week.
