The administration fee is $60. To do this, you need to find the rate of increase, or cost per month. Start by subtracting 810 by 660, to find the change of cost in 3 months. This will give you a cost of $150 for 3 months. To find the monthly fee, divide by 3, and you will get $50 a month. Now, you can subtract the total of the monthly cost for 12 months, which is $600, from $660, to get the administration fee of $60.

The equations are 660=12x+a and 810=15x+a, where x is the monthly fee and a is the one time administration. You then must subtract both equations to get 150=3x. Then simplify to get 50=x. Now that you have the monthly rate, you plug it into either equation to get the administration fee.
660=12(50)+a
660=600+a
60=a

Answer:

$3,623.84 Exact answer without rounding | $3,623.85 ~ (Approximent Answer with rounding.)

Step-by-step explanation:

Compound Interest Has a Specific Formula:

This case is Exponential Growth.

Formula: y= ab^x

You need to set up the equation.

First we need to define the rate of growth meaning what do you have to do for the 6.5%.

You need to do 100% + 6.5% = 106.5%

You need to convert the percent to a decimal which will be 1.065


Now we need to start plugging things into our formula to solve.

Your initial Starting amount was $3000

So you need to have y=3000(b)^x

We now know that the rate of growth is 1.065 so the b would be 1.065

y=3000(1.065)^x

Our power to x is our 3.5 years.

Our Equation now:

y=3000(1.065)^3

Now you need to use a calculator to do this due to the amount of decimals and digits.

Remember pemdas when doing this!!!

The answer should result to $3,623.84 but if rounded then: $3,623.85

Answer:

-(x+2)/(x+8)

Step-by-step explanation:

( x^2 -x-6)

------------------

24 - 5x -x^2

Factor out a minus sign from the denominator

( x^2 -x-6)

------------------

-( x^2 +5x -24)

Factor the numerators and the denominators

( x-3) (x+2)

------------------

-( x+8)(x-3)

Cancel like terms

  x+2

------------------

-(x+8)

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 70 p
nikklg [1K]
X = large boxes and y = small boxes

x + y = 70.....x = 70 - y
60x + 65y = 4300

60(70 - y) + 65y = 4300
4200 - 60y + 65y = 4300
5y = 4300 - 4200
5y = 100
y = 100/5
y = 20 <=== the small boxes weigh 20 lbs

x + y = 70
x + 20 = 70
x = 70 - 20
x = 50 <== and the large boxes weigh 50 lbs

Help me answer this.. plz

Answer:

2\frac{1}{30}

Step-by-step explanation:

First thing you gotta do is find the common denominator.

Do this by listing factors of the denominators:

5- 5, 10, 15, 20, 25, 30

6- 6, 12, 18, 24, 30, 36

5 and 6 both have 30 in common so that's the new denominator for all 3 of the terms.

What you do to the bottom you must do to the top.

Since you multiply 5 by 6 to get 30, you must multiply 2 and 4 by 6 as well.

Since you multiply 6 by 5 to get 30, then multiply 5 by 5 as well.

The new equation is:

\frac{12}{30} +\frac{25}{30} + \frac{24}{30} =

Now add the numerators together

The solution is \frac{61}{30}. Now simplify. 61 is prime, so you cannot change the fraction How many times does 30 go into 61? Two times. This gives us 2\frac{1}{30}.
