Traveling
miles on this taxi costs

In fact, we spend 2.50 no matter what, and then we add 3.25 (i.e. the cost of a mile) multiplied by the number of miles.
This quantity has to be less than or equal to 61, so we have

Solving for
, we start by subtracting 2.5 from both sides:

Then, we divide both sides by 3.25:

You combine everything you can, which is only 17 and 3. So your answer is 10x + 5y + 20
9514 1404 393
Answer:
(b) (-3, -1)
Step-by-step explanation:
Differences between adjacent f(x) values are ...
-31, -13, -1, +5, +5, -1, -13
The function is increasing on intervals where the differences are positive: between (-3, -11) and (-1, -1). That is ...
f(x) is increasing on (-3, -1)
If you divide 67 by 50 you are left with 1.34 if you turn that decimal into a percent it turns into 134%
