Answer: 117.5
Explanation: Assuming that after 10 years the lawn mower would have a value of 0. We can evenly divide $470 by the amount of years.
$750/10 = $75
We would then multiply 75*7.5 years to then realize the value lost over that amount of time would be $352.5, subtracting that from the original value of $470 would then be 117.5
The answer to the first part is 3 1/2 and the answer to the second question is 2/7
One solution.
They have different slopes and therefore must have one solution.
It will be b because you will have to time $3.50P140= 490
