Answer:
Company B would be a better choice.
Company B is cheaper.
Step-by-step explanation:
Let x be the rate per square foot
✔️Company A charges: $215 + $0.50x
If they are installing 400 ft² of carpet, they would be charged the following by company A,
Substitute x = 400 into the equation.
We have:
$215 + $0.50(400) = $415
They would pay $415 if they use Company A's services
✔️Company B charges: $100 + $0.75x
If they are installing 400 ft² of carpet, they would be charged the following by company B,
Substitute x = 400 into the equation.
We have:
$100 + $0.75(400) = $400
They would pay $400 if they use Company B's services .
✅Company B would be a better choice because the total charges they would pay to install 400 ft² carpet is cheaper than they would pay for Company A.

Answer:
61
Step-by-step explanation:
If there are 6 coins on each page, then the number of pages for 600 coins is ...
(600 coins)/(6 coins/page) = 100 pages
__
If 39% are empty, then 100% -39% = 61% are filled.
The number of filled pages is ...
61% × 100 = 61/100 × 100 = 61 . . . . pages filled
_____
<em>Comment about percent</em>
You can think of the percent symbol (%) and "per 100" (/100) as being interchangeable. 61% = 61/100
("Cent" is used to signify one of 100 parts. A cent is 1/100 of a dollar, for example. In land area, a cent is 1/100 of an acre. Then, "percent" can be thought of as "per cent" or "per 100 parts".)

Explanation
The given equation that represents the number of bags of sand (x) and bags of mulch (y) that can be bought with $105 is

If no bags of sand are bought, therefore x = 0
Then the number of bags of mulch that can be bought with $105 will be
Mode = number which appears the most
The mode for your question is 5
Option A
The simple interest earned over 6 years is $ 4050
<em><u>Solution:</u></em>
Martha invested a principal amount of $15,000 into a savings account that earns simple interest at a rate of 4.5% per year
<em><u>The formula for simple interest is given as:</u></em>

Where, "p" is the principal and "n" is the number of years and "r" is the rate of interest
From given,
p = 15000
r = 4.5 %
n = 6 years
<em><u>Substituting the values we get,</u></em>

Thus simple interest earned over 6 years is $ 4050
