Question

Each book in a store costs $8, and each pen costs $4. If you want to spend exactly $32, write the equation, in standard form, that represents modeling this situation. Let B represent the number of books you buy, and P represent the number of pens you buy.

Answer 1

Explanation:

Let B represent the number of books that you buy, and let P represent the number of pens that you buy.

If each book in a store costs $8 and each pen costs $4, it means that the cost of B books and P pens would be expressed as

8B + 4P

If you want to spend exactly $32, then the equation, in standard form, that represents modeling this situation is

8B + 4P = 32
