Answer 2

Answer:

The cost of 30 pens is 54 .

Step-by-step explanation:

Given information,

the cost of 24 pens is 43.20

We have to find out the cost of 30 pens

As,

The cost of 24 pens = 43.20

The cost of 1 pen = $\frac{the \: cost \: of \: 24\: pens }{24}$

The cost of 1 Pen $= \frac{43.20}{24}$

By dividing 43.20 by 24 we get

The cost of 1 pen = 1.8

The cost of 30 pens = The cost of 1 pen × 30

The cost of 30 pens = $1.8 \times 30$

The cost of 30 pens = $54$

Hence,

The cost of 30 pens is 54 .
