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.
