mark works strictly on commission of his gross sales from sellling two different products. Last month his gross sales were $94,000. If he earns 4% commission on product A and 3% on product B what were his gross sales for each product if he earned $3480 in commission?

Question

anonymous · Answer

system of equations  
first for the sales amount

A + B = 94000

second for his commission

.04(A) + .03(B) = 3480

just solve the system

Sorry, I still don't get it. Do I set up the equation:
0.04 (94000) +0.03(94000-A) = 3489?

close.... with a system of equations you want to solve one equation for one variable.. so lets solve the first one for B... we would get

B = 94000-A

now we go to the second one and plug in what we found for B so we would get
.04(A) + .03(94000-A) = 3489

now we have an equation that we can solve since B is no longer involved... there is only A
