gavmur [86]

Answer:

3.2x + 0.8y ≤ 50

Step-by-step explanation:

Mr. Ishimoto ordered math books and workbooks for his class.

Weight of each math book = 3.2 pounds

number of math books ordered = x

so, total weight of math books = 3.2x

Weight of each workbook = 0.8 pounds

number of workbooks ordered = y

so, total weight of workbooks = 0.8y

Since the total weight of the box of books cannot be more than 50 pounds, the equation would be

3.2x + 0.8y ≤ 50
