Question

Henry started the school year with 3 packages of pencils. He used 4 pencils each week. If a school year is 36 weeks, during which week will he run out of pencils?

Answer 1

We know that

• Henry started with 3 packages of pencils.

,

• He used 4 pencils each week.

,

• The school year is 36 weeks.

Assuming that each package of pencils has 8, he would have

$3\cdot8=24$

Henry has 24 pencils in total. But he uses 4 pencils each week, so let's divide

$\frac{24}{4}=6$

Therefore, Henry will run out of pencils in week 6.
