Answer 2

Answer:

The cost of 25 pens is $ 587.50

Step-by-step explanation:

Given information,

The cost of 18 pens is $ 423

We have to find out the cost of 60 pens

As,

The cost of 18 pens = 423

The cost of 1 pen = $\frac{the \: cost \: of \:18\: pens }{18}$

The cost of 1 Pen $= \frac{423}{18}$

By dividing 423 by 18 we get

The cost of 1 pen = 23.50

The cost of 25 pens = The cost of 1 pen × 25

The cost of 25 pens = $23.50 \times 25$

The cost of 25 pens = $587.50$

Hence,

The cost of 25 pens is $ 587.50
