The cost of 8 muffins and 2 quarts of milk is $18. The cost of 3 muffins and 1 quart of milke is $7.50. How much does 1 muffin and 1 quart of milk cost?
Let x equal the cost of one muffin and y equal the costĀ of quart of milk
8x+2y=18
3x+y=7.50
See if you can solve it from there. If not let me know
