Answer:
Step-by-step explanation:
The parameters given are;
The amount Mary earns annually = $28,000
The amount Mary grossed during a week = $655.58
The amount Mary had sold during the week to make the amount grossed during the week = $1673.19
Given that Mary makes $28,000 per year
Therefore;
The amount Mary earns per week = Amount earned per year/52
The amount Mary earns per week = $28,000/52 = $538.46
The amount extra she made on commission = $655.58- $538.46= 1$117.12
The commission rate = Commission earned/(Amount of merchandise sold)×100
The commission rate = 117.12/1673.19 × 100 = 6.99%
Her commission rate = 6.99%
