Question

A pencil cost x peso each. If the total cost of 15 pencils is 120 pesos, how much does each pencil cost?

Answer 1

Solution:

Cost of 1 pencil$=x$ peso

Total number of pencils$=15$

Total cost of 15 pencils$=120$

So, $15x=120$

$\Rightarrow x=\dfrac{120}{15}=8$ [Dividing by 15]

Hence, the cost of each pencil is 8 pesos.
