Answer 1

The cost per pound of mac and cheese is $2.50.

Abdullah gets 0.4 pounds of mac and cheese per dollar.

Abdullah could buy 8 pounds of mac and cheese for $20.

Step-by-step explanation:

(1) To find the cost per pound of mac and cheese, divide the total cost by the number of pounds purchased. $7.50 divided by 3 pounds equals $2.50 per pound.

(2) To find how much mac and cheese Abdullah gets per dollar, divide the number of pounds by the total cost. 3 pounds divided by $7.50 equals 0.4 pounds per dollar.

(3) To find how much mac and cheese Abdullah could buy for $20, divide the total amount of money by the cost per pound. $20 divided by $2.50 per pound equals 8 pounds of mac and cheese.
