The answer is D. You do 21000-7000=14000. This is the excess that he earns 3% on. Then you multiply 14000 by .03 and you should get 420. Add 420 to his original 400 for a total of 820.
Robert Bryan, Jr., earns $400 per week plus 3% of sales in excess of $7,000. If Robert sells $21,000, how much are his weekly earnings?
If Robert receives 3% of sales over $7,000 subtract that amount from his sales to find out what amount he can earn commission off of first.
$21,000 - $7,000 = $14,000
Next, take the amount he can earn commission on and multiply it by 3%:
14,000 x 3% = $420
The final step is to add his weekly commissions to his weekly earnings of $400:
$420 + $400 = $820
$820 is Roberts weekly earnings.
