Determine equivalent ratios:
First, we simplify the ratio to the least possible
By comparison with the given options, we have A and B as answer.
See Proof Below
Proof: A
Compare this to the simplified ratio (given), we have:
=
Proof B
Simplify the ratio to the least possible
Compare this to the simplified ratio (given), we have:
=
Answer:
b= \frac{1}{2ha} -c
Step-by-step explanation:

Answer:
- rate of change: $8 per hour; the per-hour rental charge
- initial value: $75; the deposit on the machine
Step-by-step explanation:
The cost to rent the machine is given as ...
total cost = deposit + ($8 /hour)×(number of hours)
The cost for 5 hours is given ans $115, so we have ...
115 = deposit + 8(5)
75 = deposit . . . . . . . . subtract 40
__
The "rate of change" is given as $8 per hour, the hourly rental charge.
The "initial value" is called <em>the deposit</em>. It is found to be $75.
