Chris can be paid in one of two ways. plan a is a salary of $350 per month, plus a commission of 7% of a sales. plan b is a salary of $436 per month, plus a commission of 5% of sales. for what amount of sales is chris better off selecting plan a

Let's say, the total sales is "x"... .so hmm on Plan A, he gets 350 plus 7% of "x", well, 7% is just (7/100) * x or 0.07x

now, on Plan B, he gets 436 plus 5% of "x", 5% of "x" is (5/100) * x, or 0.05x

he's better off with A, only if A is greater than B, namely, A > B



and surely you know how much that is.

The answer would be d i think but i’m for sure it is not a and c
