Answer:

Step-by-step explanation:
Given the expression: P= I + HB
Where:
- P = cost of the phone Liam is saving for.
- I = amount of money he started with.
- H = number of hours he babysits
- B = hourly rate for babysitting.
We want to find an expression for H, the number of hours Liam will need to babysit to save enough money for a cell phone.
Our goal is to isolate the variable H in the expression P= I + HB.
P= I + HB
Subtract I from both sides
P-I=I-I+HB
HB=P-I
Divide both sides by B

Answer:
The answer is 75 inches.
Step-by-step explanation:
If Alice is 10 inches, she is 2/3 as tall as the door. At her regular height, to be 2/3 as tall as the door the door would have to be 75 inches high.
So, let's add up the total amount he made:
120 + 80 + 75 = 275
If he withdrew $30:
275 - 30 = 245
Tom will have $245 at the end of June
