shelby had $18.50. She spent $7.25 at the car wash. Write an expression that shows how much she spent.
You have just said that she spent $7.25. There is no need for an equation.
However, if you want to know how much she has left:
$18.50 - $7.25 = ?
I hope this helps. Thanks for asking.
(18.50 -7.50)
To write an expression that shows how much Shelby spent, we need to subtract the amount she spent from the amount she had.
Shelby spent $7.25 at the car wash.
So, the expression that shows how much she spent can be written as:
$18.50 - $7.25
To simplify this expression, subtract the values:
$18.50 - $7.25 = $11.25
Therefore, Shelby spent $11.25.
