Answer:

The cost of 80 pencils is 1040

Step-by-step explanation:

Given information,

The cost of one dozen pencil is 156.

We have to find out the cost of 80 pencils.

As we know that

One dozen equal to 12 substance.

So, One dozen of pencil means 12 pencil.

The cost of 12 pencils = 156

The cost of one pencil = $\frac{the \: cost \: of \: 12 \: pencile}{12}$

The cost of 1 pencil = $\frac{156}{12}$

The cost of 1 pencil = 13

The cost of 80 pencils= The cost of 1 pencil × 80

The cost of 80 pencils = 13× 80

The value of 80 pencils = 1040
