Step-by-step explanation:
Given:
Ben orders a case of his favorite macaroni and cheese.
The case contains 18 same size boxes that weigh a total of 7.2 pounds.
Now, to find the weight of each box of macaroni and cheese.
Let the weight of each box be [tex]x.[/tex]
Number of boxes in a case = 18.
The total weight = 7.2 pounds.
According to question:
[tex]x\times 18=7.2[/tex]
[tex]18x=7.2[/tex]
Dividing both sides by 18 we get:
[tex]x=0.4\ pounds.[/tex]
Therefore, the weight of each box is 0.4 pounds.
The equations which represents the weight, in pounds,of each box of macaroni and cheese is 2.5 pounds
Weight of each box of macaroni and cheese = Total boxes in a case of macaroni and cheese ÷ Total weight of the case
x = 18 ÷ 7.2
7.2x = 18
x = 2.5 pounds
