The pen costs $1.05 if its one buck more than the pen because 0.05 plus 0.05 is 0.10 plus a dollar that equals $1.10

You should solve it algebraically as follows:

Let the cost of the pencil = P, then:

The cost of the pen =P + 1. So, we have:

P + P + 1 =$1.10

2P + 1 =$1.10 Subtract 1 from both sides

2P =$0.10 Divide both sides by 2

P =$0.10 / 2

P = $0.05 cents - the cost of the pencil

$1 + $0.05 =$1.05 - cost of the pen.
