Answer 2

Answer:

The cost of 14 pens is 161 .

Step-by-step explanation:

Given information,

the cost of 12 pens is 138

We have to find out the cost of 14 pens

As,

The cost of 12 pens = 138

The cost of 1 pen = $\frac{the \: cost \: of \: 12\: pens }{12}$

The cost of 1 Pen $= \frac{138}{12}$

By dividing 138 by 12 we get

The cost of 1 pen = 11.50

The cost of 14 pens = The cost of 1 pen × 14

The cost of 14 pens = $11.50 \times 14$

The cost of 14 pens = $161$

Hence,

The cost of 14 pens is 161 .
