$1240 - $786 = $454
$454 divides by $9.50 which is $47.79 which is almost $48
There are 12 players so each must sell 4 candles
12 and 28, because
n + (<u><em>2n + 4</em></u>) = 40
<u><em>3n + 4</em></u> = 40
<em><u>3n = 36 n = 12</u></em>
<u><em>12x2 + 4 = 28</em></u>
<u>28</u> is the larger number.

Answer: The equation is h(x) = 45(1/5)^x
This is the same as h(x) = 45(0.2)^x because 1/5 = 0.2
=======================================================
Explanation:
We'll start with y = a*b^x, and plug in x = 0 to find that,
y = a*b^x
y = a*b^0
y = a*1
y = a
The table says that y = 45 is the case when x = 0. So that must mean a = 45.
The value of ''a' is the y intercept and it's the initial value.
---------
So the equation y = a*b^x updates to y = 45*b^x
Let's plug in (x,y) = (1,9) and solve for b
y = 45*b^x
9 = 45*b^1
9 = 45b
45b = 9
b = 9/45
b = 1/5
b = 0.2
Therefore, the equation in fraction form is y = 45(1/5)^x
That same equation in decimal form is y = 45(0.2)^x
---------
To verify the equation, plug in various values of x and you should get y values that are shown in the table.
For instance, plug in x = 2 to find that
y = 45(0.2)^x
y = 45(0.2)^2
y = 45(0.04)
y = 1.8
which matches with the table. That verifies the 5th row. I'll let you verify the other rows.
we have asked to represents
3 tenths and 9 hundredths as a decimal.
As we know the tenths place is the first place on right side of the decimal.
Also we know that hundredths is the second place on right side of the decimal.
since the problem says
3 tenths----> it mean the first position on the right side of the decimal.
9 hundredths.......> it mean the second position on the right side of the decimal.
Hence the decimal representation of the number is 0.39
