Its a we know its this cause its rational and if its a rational number it is also an integer and a whole number
<u>Answer:</u>
$50 and $115
<u>Step-by-step explanation:</u>
We know that,
the sum of the two rates = $165 per hour
Let x and (165 - x) represent the $/hour of the 15hr and 5hr mechanics respectively.
Then combining their charges together to get:

Solving for x to get:



So the rate charged per hour by one mechanic is $50 and for the other mechanic =
$115.
Answer:
First, I think the right formula is:

A) We first derive the formula given above:

V'(t) represent the drain rate of the tank volume.
B) the units is: gallons/time
C) at V'(10) = 100000/60 = 1666.66 gallons/time.
because the formula V'(t) is constant so it doesn't depend of time.
