you are spending $55 for books, pencils, and erasers. Books (b) cost $7.50, Pencils (p) cost $3, and erasers (e) cost $2 each. write an equation the represents this situations.
The equation that represents this situation is:
7.50b + 3p + 2e = 55
Let's use the variables b, p, and e to represent the number of books, pencils, and erasers, respectively.
The cost of books (b) is $7.50 per book, so the total cost of books would be 7.50b.
The cost of pencils (p) is $3 per pencil, so the total cost of pencils would be 3p.
The cost of erasers (e) is $2 each, so the total cost of erasers would be 2e.
Since the total cost of books, pencils, and erasers is $55, the equation representing this situation would be:
7.50b + 3p + 2e = 55
To write an equation that represents the given situation, we can assign variables to each item - books, pencils, and erasers.
Let b represent the number of books.
Let p represent the number of pencils.
Let e represent the number of erasers.
The cost of each item is as follows:
Books cost $7.50, so the total cost of books would be 7.50b.
Pencils cost $3, so the total cost of pencils would be 3p.
Erasers cost $2 each, so the total cost of erasers would be 2e.
The total cost of all the items combined is $55. Therefore, the equation representing the situation is:
7.50b + 3p + 2e = 55
