Harry buys 1/4 pound of american cheese at a cost of x dollars per pound. if he pays $12.25 for 2.5 pounds of american cheese, what is the cost per pound of the cheese?

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
