Felipe loves candy. One week, he went to
the candy store and bought 1.4 pounds of
M&M's, and 2.2 pounds of Skittles, and
spent a total of $2.48. The next week he
returned to the same store, and bought 1.6
pounds of M&M's and 1.8 pounds of
Skittles, and spent $2.37. What was the
price per pound of the M&M's and of
the Skittles?
