Answer:
After 50 minutes, the price charged by each company will be the same.
Explanation:
First, we would have to set up an equation for each of the cleaning services. We can set our variable up as "m" for "minute" because that is the unknown value.
<h2>

</h2>
To see how many minutes have to pass for the price charged by each service to equal each other, we must literally make the equations equal each other.
<h2>

</h2><h2 />
Now, to solve for <em>m</em>, we first combine like terms.

Subtract.

Divide both sides by 0.1 to isolate <em>m</em>.


Therefore, the price charged by each company will be the same after 50 minutes.
I hope this helps!
Answer:
The set of all positive integers equal to or greater than 1
Step-by-step explanation:
n can take on the integer values 1 ... ∞
The formula for the nth term is a(n) = a(1) + 2(n - 1)
First term: n = 1. Then a(1) = 3 + 2(0) = 3 (as expected).
5th term: n = 5. Then a(5) = 3 + 2(5 - 1) = 3 + 8 = 11
...
and so on.
