Answer:
You can only buy 29 pencils with $2.95
Each pencil costs $0.10. You'd be able to buy 29 pencils and keep $0.05
You can't buy an extra pencil with $0.05. You need $0.10 to buy a pencil.
Step-by-step explanation:
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
