Answer:
Sonny's weekly gross salary was $575
Step-by-step explanation:
Equations
Sonny works as a furniture salesman and earns a base weekly salary of $350 plus a 6% commission on sales.
This can be modeled by the function:
E(x)=350+0.06x
Where x dollars are his weekly sales.
We are given the total sales for a week are x=$3750, so his earnings are:
E(3750)=350+0.06*3750=575
Sonny's weekly gross salary was $575
