Answer:

The cost of 7 pencils is 73.5

Step-by-step explanation:

Given information,

The cost of 1 pencil is 21/2

We have to find out the cost of 7 pencils.

As,

The cost of 1 pencils = \frac{21}{2}

The cost of 7 pencils= The cost of 1 pencil × 7

The cost of 7 pencils = \frac{21}{2} × 7

The value of 7 pencils = 10.5 \times 7

The value of 7 pencils = 73.5

Hence,

The cost of 7 pencils is 73.5
