Question

Jennifer had some money in her pocket. She spent $1.35, which left her with $2.30. Write an equation or an inequality to find the original amount of money she had in her pocket.

Answer 1

Equation: X-1.35= 2.30

Value of X: x=3.65

Explanation:

You can choose whatever variable you want to represent the original amount of money Jennifer had in her pocket. I decided to use X as my variable.

If X represents the original amount of money Jennifer had in her pocket, then I can write this equation:

X-1.35= 2.30

Essential what this equation shows is that Jennifer spends $1.35 of what she originally has, which is x. After she spends that she's left with $2.30. This is how we solve for x, also known as the original amount Jennifer had in her pocket:

X-1.35= 2.30

(we will add 1.35 to each side because we what to balance out the equation and the inverse operation of subtraction is addition)

X= 3.65

So Jennifer originally had $3.65 in her pocket before she spent the $1.35

( Hope this helps :). Let me know if there's any confusion in my answer/explanation)
