Greg earns a salary of $300 per week plus an additional 6% commission on his sales. If his weekly salary
increases by $50 and his commission increases to 7%
how much will Greg earn if his weekly sales are
$4,000?

Given :

Greg earns a salary of $300 per week plus an additional  6% commission on his sales.

To Find :

If his weekly salary  increases by $50 and his commission increases to 7%  how much will Greg earn if his weekly sales are  $4,000.

Solution :

New weekly salary, S = $( 300 + 50 ) = $350 .

New commission on $4000 sales :

.

Therefore, total earning T = S + C = $( 350 + 280 ) = $630 .

Hence, this is the required solution.
