Question

Mario sells electronics at Big Box Electronics Store. He is paid a salary of $350 a week plus 5% commission on his sales. Write an equation in the form E=mS+b

Answer 1

It appears that E would represent his total earnings (with commission), m would represent his commission rate or percent ( usually in decimal form), S is the amount of his sales, and b is the weekly salary he gets without commission.

For this problem, he would earn (NOTE - 5% is equal to 0.05):

E = mS + b

E = 0.05* S + 350

Once you know his sales, you can multiply by 0.05 and add $350 for his total earnings that week.
