Edgar Anderson earns $200 a week plus a 15% commission on all sales over $1,000. If Mr. Anderson's sales for one week are $2,500, what is his gross pay for that week.

A. 575

B. 525

C. 350

D. 425

Edgar Anderson earns a fixed amount of $200 per week.

He also earns a commission of 15% above any sales over $1000

In the given week the sales has amounted to $2500

So,

Amount over which Edgar Anderson will earn 15% interest = (2500 - 1000) dollars

= 1500 dollars.

Hence interest earned by Edgar Anderson in the week = [1500 * (15/100) ] dollars

= (15 * 15) dollars

= 225 dollars

The gross pay of Edgar Anderson = (200 + 225) dollars

= 425 dollars

Hence the correct option for this question is option 'D'.
