Karla wants her home cleaned. Molly maids charges $10 a day plus $0.35 per minute. Sally scrubs charges $15 a day plus $0.25 per
Olenka [21]

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>Molly Maids: 10+0.35m\\ Sally Scrubs: 15+0.25m</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>10+0.35m=15+0.25m</h2><h2 />

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

10-15=0.25m-0.35m

Subtract.

-5=-0.1m

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

m=5/0.1

m=50

Therefore, the price charged by each company will be the same after 50 minutes.

I hope this helps!

Given the arithmetic sequence an = 3 + 2(n − 1), what is the domain for n?
yKpoI14uk [10]

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.
