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.
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
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.
To find the cost of each shirt, we can start by assigning a variable to represent the cost of one of the shirts. Let's say the cost of one shirt is "X" dollars.
We are given that one shirt costs $3.50 more than the other shirt. So we can represent the cost of the other shirt as "X + $3.50".
Since Kathleen spent a total of $30.50 on both shirts, we can set up an equation using the given information. The equation would be:
X + (X + $3.50) = $30.50
To solve this equation, we need to combine the like terms. Combining "X" and "X" gives us "2X". The equation becomes:
2X + $3.50 = $30.50
Next, we want to isolate the variable "X". To do that, we need to get rid of the $3.50 on the left side of the equation. Since $3.50 is added to "2X", we can subtract $3.50 from both sides of the equation:
2X + $3.50 - $3.50 = $30.50 - $3.50
Simplifying the equation:
2X = $27
Now, to find the value of "X", we need to isolate it. Since "2X" means 2 multiplied by "X", to get the value of "X", we can divide both sides of the equation by 2:
2X/2 = $27/2
Simplifying further:
X = $13.50
So, one shirt costs $13.50. Since the other shirt costs $3.50 more, we can add that amount to the cost of the first shirt:
Cost of first shirt + $3.50 = $13.50 + $3.50 = $17.00
Therefore, one shirt costs $13.50 and the other shirt costs $17.00.
