Question

You are spending $55 for books, pencils, and erasers. Books (b) cost $7.50, pencils (p) cost $3, and erasers (e) cost $2, each. Which equation represents this situation

Answer 1

Answer:

7.50b + 3p + 2e = 55

Step-by-step explanation:

Since, the cost of each book = $7.50,

⇒ The cost of b books = 7.50b dollars

the cost of each pencil = $3,

⇒ The cost of p pencil = 3p dollars

the cost of each eraser = $2,

⇒ The cost of e eraser = 2e dollars

So, the total cost of b books, p pencils and e erasers = 7.50b + 3p + 2e

According to the question

7.50b + 3p + 2e = 55

Which is the required equation.

Answer 2

$((b \times 7.50) + (p \times 3) + (e \times 2)) = 55$
