Question

If 100 pencils can be sold for $90, then how many pencils are needed to earn $8500?

Answer 1

Step-by-step explanation:

You can set up a proportion.

Let x be the number of pencils needed.

$\frac{100}{90} = \frac{x}{8500}$

Solve for x.

x = 9444.44 pencils (round it up to 9445 pencils if you need a whole number)
