Question

Arnold had $37 to spend pens & pencils. The pens were $1 more than the pencils. He Bought 1 pen and 3 pencils. How much did the pens cost

Answer 1

The pens cost $10 if the total was $37

Work:

Pen: ||||||||||
Pencil: |||||||||
Pencil: |||||||||
Pencil: |||||||||

Basically the division groups you probably learned in elementary.


Because the question mentioned that pens were $1 more than pencils. Pens automatically start with one extra in sorting.

9(3) + 10
= 37

(9+9+9) + 10
= 37

Above adding everything together to get our answer.
