Answer:
We conclude that eighty percent of bike tires last at most 14.4 months.
Step-by-step explanation:
We know that a pair of bike tires can last 18 months if used every day.
We calculate how much eighty percent of the tire will last in months.
We have the following proportion:
We conclude that eighty percent of bike tires last at most 14.4 months.

Answer:
You can't
Step-by-step explanation:
This is just an expression that has been simplified. You would be able to solve for x if this was an equation.
149.5 +15x=149.5 +15x get variables to one side
-15x
149.5=149.5
there the same
So there are no for x that can make this equation true
The exponential function f(x) can represent growth or decay
The value of f(14) is 226.07
<h3>How to determine the value of f(14)?</h3>
The given parameters are:
f(-2) = 25 and f(7) = 85
An exponential function is represented as:
f(x) = ab^x
So, we have:
ab^-2 = 25
Also, we have:
ab^7 = 85
Divide both equations.
This gives
b^9 = 3.4
Take the 9th root of both sides
b = 1.15
Recall that:
ab^7 = 85
This gives
a* 1.15^7 = 85
Solve for a
a = 31.95
So, the exponential function is:
f(x) = 31.95 * 1.15^x
Substitute 14 for x
f(14) = 31.95 * 1.15^14
f(14) = 226.07
Hence, the value of f(14) is 226.07

Answer: $171.31
<u>Step-by-step explanation:</u>
A = P(1 - r)ⁿ
Given: P = 200, r = 1.1% (.011), n = 14
A = 200(1 - .011)¹⁴
= 200(.989)¹⁴
= 171.308
Since we are talking about money, round to two decimal places.
