Answer:
22.50
- 15.00
_______
7.50
Step-by-step explanation:
She still owes $7.50
15/3 + 4/3 = 19/3
All you have to do is subtract 4/3 from 19/3 to get 15/3
By intuition, the function of y with respect to x will be:
y = 4x
You can prove this by substitute in each pair of values of x and y
So the constant of relationship is 4
In order to make b the subject of this equation, we must isolate it on the left side. We can do this by following these steps:

Subtract b from both sides


Subtract P from both sides


Now, we have isolated b, but it is negative. We can fix this by multiplying both sides of the equation by -1.


Which is your final answer.
