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 :
[tex]C=\dfrac{4000\times 7}{100}= \$280[/tex] .
Therefore, total earning T = S + C = $( 350 + 280 ) = $630 .
Hence, this is the required solution.
