Question

Mr. Ishimoto ordered x new math books and y new workbooks for his class. The total weight of the box of books cannot be more than 50 pounds. If each math book weighs 3.2 pounds and each workbook weighs 0.8 pounds, which inequality represents the maximum number of each type of book that can be shipped in a single box?

Answer 1

3.2x + 0.8y ≤ 50
I hope this is a choice.

Answer 2

Answer:

$3.2x + 0.8 y \leq 50$

Step-by-step explanation:

GIVEN : x denotes the no. of new math books .

              y denotes the no. of new workbooks .

              Each math book weighs 3.2 pounds.

              Each workbook weighs 0.8 pounds.

              Total weight of the box of books cannot be more than 50 pounds.

Solution :

Since , the no. of new math books is x  and each math book weighs 3.2 pounds .

So, total weight of maths books is 3.2x pounds.

Since , the no. of new workbooks is y and each workbook weighs 0.8 pounds.

So, total weight of  workbooks  is 0.8y pounds.

Since, Total weight of the box of books cannot be more than 50 pounds and box contains maths and workbooks

So, inequality that  represents the maximum number of each type of book that can be shipped in a single box

⇒$3.2x + 0.8 y \leq 50$
