Jessica is stacking items on a shelf. she has large books that weigh 5 pounds each and medium books that weigh 3 pounds each. the shelf should hold at most 50 pounds. let x represent the number of large books. let y represent the number of medium books. which inequality represents this situation?

5x + 3y ≤ 50

Step-by-step explanation:

Given,

The weight of each large book = 5 pounds,

And, the weight of each medium book = 3 pounds,

Thus,

The total weight in pounds of x large books and y medium books = x × weight of each large book + y × weight of each medium book

= 5x + 3y

According to the question,

Total weight ≤ 50 pounds  

( Note : at most = less than equal )

⇒ 5x + 3y ≤ 50

Which is the required inequality.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
