Question

If a notebook costs Rs p and a pencil costs Rs 3, then the total cost (in Rs) of two note books and one pencil. Give expression.

Answer 1

Step1: As the Cost of $2$ notebooks
Cost of one notebook $Rs.p$
Then, the cost of two notebooks $=2\times p=Rs.2p$
Step2: The total cost
Also,the cost of one Pencil $=Rs.3$
$\mathrm{Total}\mathrm{cost}=\mathrm{Cost}\mathrm{of}\mathrm{two}\mathrm{notebooks}+\mathrm{cost}\mathrm{of}\mathrm{one}\mathrm{pencil}$
Therefore, the total cost of two notebooks and one pencil $=2p+3$
Therefore the required expression is $2p+3$
