Answer:
The total earning for the week is $546
Step-by-step explanation:
Let us solve the question
∵ Harper sells appliances
∵ She makes a weekly salary of $450 plus a 3% commission on her
total sales for the week
→ That means there is a fixed amount + amount depends on her sales
∴ Her total earning = 450 + 3% of total sales
∵ 3% = 3/100 = 0.03
∴ Her total earning = 450 + 0.03 (total sales)
∵ Her total sales this week were $3,200
→ Substitute it in the equation above
∴ Her total earning = 450 + 0.03(3,200)
∴ Her total earning = 450 + 96
∴ Her total earning = 546
∴ The total earning for the week is $546
