Answer:
The value of the machine after two years is approximately $466.6
Step-by-step explanation:
The details of the valuation of the machine are;
The function giving the machine value, 'V', is V =
Where;
C = The original cost of the machine
r = The depreciation rate
t = The time the machine has been in service
When C = $576, r = 0.1, t = 2 years, we have;
Therefore, the value of the machine that costs $576 having a depreciation of 0.1 after 2 years is, V = $466.58
By rounding to the nearest cent, we have, V = $466.6.
Answer:
It will take 3.6 hours to wax a car if they work together.
Step-by-step explanation:
Calvin one hour work =
Alvin one hour work =
To find out how much they can do together per hour,
We have to add and
=
= --------------(1)
They can do of the job per hour.
If "t" is the time taken to finish the job together, then one hour work
------------------------(2)
Now we have to find the value of "t" by setting the expression (1) and (2) equal.
It can solve by flipping the equation;
t = 3.6 hours
It will take 3.6 hours to wax a car if they work together.
