**Ms. Sue**, Wednesday, November 14, 2012 at 10:55pmX = 1 shirt

X + 3.50 = the other shirt

2x + 3.50 = 30.50

Subtract 3.50 from both sides.

2x = 30.50 - 3.50

2x = 27

Divide 27 by 2.

x = 13.50

One shirt is $13.50.

13.50 + 3.50 = 17.00

13.50 + 17.00 = $30.50

**Alexa**, Wednesday, November 14, 2012 at 11:02pmThe equation would be 2x + 3.50 = 30.50.

Basically, x represents the shirts and since there are two shirts, we multiply x by 2.

$3.50 is added because one shirt is $3.50 more than another.

Isolate the variable.

Subtract 3.50 from 30.50 which would equal 27.

Then, divide 2 from both sides so x = $13.50.

To check your work, plug everything back into the equation.

So, 2(13.50) + 3.50 = 30.50.
