Question

do not know how to get answer on kathleen spent $30.50 on two shirts. One shirt cost $3.50 more than the other. How much did each shirt cost?How do you get the answer for X +X+3.50 = 30.50. Trying to explain how to get answer to a 5th grader.

Answer 1

X = 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

Answer 2

The 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.
