A= 630+.14S B=1260+.07S so if you want A to be greater than write the equation as an inequality like this 630+.14>1260+.07S and solve for S subtract .07S and 630 from both sides and you end up with .07S>630 so S>9000... so anything above $9000 dollars in sales and company A's offer will be better.

Another way to state the problem is "What level of
sales makes the two offers equal?"
Let = the number of sales

After 9000 sales, offer A becomes the better deal
