Answer:
y = 1/4x -3
Step-by-step explanation:
The inverse relation can be found by interchanging y and x, then solving for y.
x = 4y +12
x = 4(y +3) . . . . factor out 4
x/4 = y + 3
x/4 -3 = y
y = (1/4)x -3 . . . . the inverse relation
Answer:
$0.187 per mile
Step-by-step explanation:
The sum of the expenses for the year is ...
$1,187.25 +$118.80 +$300.00 +$75 +$614.80 +$34.90 +$1,780.00
= $4110.75
Then the cost per mile is ...
cost/miles = $4110.75 / 21986 ≈ $0.18697
The cost per mile is about $0.187, or 18.7¢ per mile.
__
If you need whole cents, that's about $0.19 per mile.
