Where P is the amount Larry will get paid, t is the time worked and S is the amount of sales he generated that week.  This was derived from the fact that 11.25 is the slope and 0.045S is the y-intercept.  By plugging in those values we have:

This is because you divide 1.49 over 10 like so: 1.49/10 = 0.149, then round this to the nearest penny to get 0.15
0.15 dollars = 15 cents
so basically whatever this item is, it costs 15 cents per item
