Answer:
The correct answer is $632.5.
Step-by-step explanation:
Mae Ling's fixed weekly salary at a gift shop is $325.
She is given an additional commission on sales.
Given that in a week, Mae Ling sold $4,100.
Commission earned by her is 7.5% of 4,100 = $307.5.
Mae Ling's total earning in the week is $(325 + 307.5) = $632.5.
Therefore this weekly's earning by Mae Ling is given by $632.5.
