Answer :
P=Pencils(s)
n=Number of pencils that can be bought for $2.95
-------------------
nP=$2.95
----------------
But 6P=$0.59
So P=($0.59)/6
------------------
Therefore:
n($0.59/6)=$2.95
n=($2.95)/($0.59/6)
n=30
n=Number of pencils that can be bought for $2.95
-------------------
nP=$2.95
----------------
But 6P=$0.59
So P=($0.59)/6
------------------
Therefore:
n($0.59/6)=$2.95
n=($2.95)/($0.59/6)
n=30
