Edgar Anderson earns $300 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?

Basic amount that Edgar Anderson earns per week = $300

Sales of Mr. Anderson for one week = $2500

Percentage of commission on sales above $1000 = 15%

Then

Amount of commission

earned for the week = [2500 - 1000] * (15/100) dollars

= 1500 * (15/100) dollars

= 15 * 15 dollars

= 225 dollars

Then

Gross pay of Edgar Anderson for the week = (300 + 225) dollars

= 525 dollars

So the gross pay of Edgar Anderson for the week is $525.
