Last week Lisa had gross earning of $441.30. Cathy receives a base salary of $375 and a commision on sales exceeding her quota of $5000. What is her rate of commision if her sales were $6560?

4.25%

Step-by-step explanation:

Step 1: Calculate the commission paid

Commission = Gross earning - base salary

Commission = 441.3 - 375

Commission = 66.3

Step 2: Calculate the commission sales

Commission sales = Total sales - quota sales

Commission sales = 6560 - 5000

Commission sales = 1560

Step 3: Calculate the rate of commission

x% of 1560 = 66.3

x% * 1560 = 66.3

x% = 0.0425

x = 4.25%

Therefore, the rate of commission was 4.25%.
