You can put this solution on YOUR website!
Suppose he sold all medium-size drinks
That would be 1.15%2A40+=+46dollars worth
and that's too much
Her's a chart to find # drinks that total $45.25:
sm - med - lg - cost
1 -- 39 -- 0 -- 45.85 (still too high)
2 -- 38 -- 0 -- 44.70 (now too small)
2 -- 38 -- 1 -- 46.00 (too high again)
2 -- 37 -- 1 -- 45.85 (close, but too high)
3 -- 37 -- 0 -- 45.55 (closer, but high)
3 -- 36 -- 1 -- 45.70 (higher still)
4 -- 36 -- 0 -- 45.40 (closest yet, a little high)
4 -- 35 -- 0 -- 44.25 (I need 1 more sm drink)
5 -- 35 -- 0 -- 45.25 Bingo
-------------------------
5 small drinks and 35 med drinks were sold
Any other way that works is OK, too
