On the 4

On the way to playing disc golf with his two boys, Mr. Smith purchases 3 muffins and 2 bottles of water, totaling $9.75. The following week he only has Asher with him, so he purchases 2 muffins and 1 bottle of water totalling $6.00.
What is the cost of one muffing? What is the cost of one bottle of water?

Correct result:

m =  2.25
w =  1.5


3m+2w = 9.75
2m + 1w = 6.00

3•m+2•w = 9.75
2•m + 1•w = 6.00

3m+2w = 9.75
2m+w = 6

m = 9/4 = 2.25
w = 3/2 = 1.5
