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