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?
○ 3.2x + 0.8y < 50
○ 3.2x + 0.8y ≤ 50
○ 0.8x + 3.2y < 50
○ 0.8x + 3.2y ≤ 50

Explanation:

Step1: Calculate total math book weight

Total weight of math books: $3.2x$

Step2: Calculate total workbook weight

Total weight of workbooks: $0.8y$

Step3: Combine weights with total limit

Total weight ≤ 50, so $3.2x + 0.8y \leq 50$

Answer:

3.2x + 0.8y ≤ 50
