If they both cost 1.10 then add 1.00 two the 1.10 to get the answer of

1.10

+ 1.00

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.

True does not require that much but at least she proves her math and gives a detailed expination of her math. Its detailed so it could help someone through the process if wanting to solve this problem.

Well it kind of does depend on where in math your looking at too.
