Sam and David were selling bottles to raise money for a 6th grade pizza party. Sam sold 5 water bottles for every three water bottles David sold. together they sold 160 water bottles. how many did each scholar sell?

3 6 9 12 15 18 21 24 27 30 33 36 39 42 45 48 51 54 58 61

5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 95 100

I wrote the numbers down for 5 Sam sold and 3 David sold.

100 Sam sold, and David sold 61, although there's one more ... It's something to start with.
