Question

For what amount of monthly sales is plan A better than plan B if we assume that Mikes sales are always more than $9,000.00? write your answer in an inequality involving X where x represents the total monthly sales

Answer 1

We will have that the expression A & B are given by the following equations respectively:

`800+0.12x`

&

`950+0.15x`

Now, we solve for "x" the number of sales:

`950+0.15x=800+0.12x\Rightarrow950-800=0.12x-0.15x`
`\Rightarrow150=-0.03x\Rightarrow x=-5000`

So, for no amount of months is salary A better than salary B.
