Find the the amount of interest per year. Since $567 were earned over 6 years, you divide the interest earned by the number of years it took to accumulate it:
$567/6 years = $94.5/year
Divide that by the interest rate which the interest rate needs to be in decimal form:
$94.5/.0525 = $1800
Hypotenuse ² =(leg1)² +(leg2)²
h²=6²+8²=36+64=100
√(h²)=√(100)
h=10
Using the Fundamental Counting Theorem, the number of possible telephone numbers is given by:
a) 900,000.
b) 78,125.
c) 10,000.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with
ways to be done, each thing independent of the other, the number of ways they can be done is:

For item a, a multiple of 100 means that the last two digits are 00, hence the parameters are:

Hence the number is:
N = 9 x 10^5 = 900,000.
For item b, odd digits are 1, 3, 5, 7 and 9, hence the parameters are:

Hence the number is:
N = 5^7 = 78,125.
For item c, if the first 3 digits are 277, the parameters are:

Hence the number is:
N = 10^4 = 10,000.

Answer:
It would cost <em>n</em> people $<em>nd</em> to play Decimal Decisions and $<em>nr</em> to play Ratio Rage. So, it would cost <em>n</em> people $<em>nd</em> + $<em>nr</em>= $2<em>n</em>(<em>d</em> + <em>r</em>).
<em>d</em>= Decimal Decisions and <em>r</em>= Ratio Rage
You didn't give a price for either game, so I just did variables in place of actual cost. Hope this helps!
