The expression that shows the change in the amount of money Belle's dad has is (x - 25) and this can be determined by forming the linear equation in one variable.
Given :
Belle's dad lends her $10. Then Belle borrows another $15 from him.
The following steps can be used to determine the expression that shows the change in the amount of money Belle's dad has:
Step 1 - Let the total amount of money Belle's dad have be 'x'.
Step 2 - Then it is given that Belle's dad lends her $10. So the expression becomes:
= x - 10b
Step 3 - Now, it is also given that Belle borrows another $15 from her dad. So, the above expression becomes:
= x - 10 - 15
Step 4 - Simplify the above expression.
= x - 25
So, the expression that shows the change in the amount of money Belle's dad has is (x - 25).
