The owner of a ski resort estimates that a new 4-person ski lift will cost $5,500,000. The owner begins making payments on March

<h3>What is compound interest?</h3>

Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest.

A = P(1 + r/n)^{nt}

P =5,500,000

r =4%= 0.004

n =4

t= 5 years.

Now,

A = P(1 + r/n)^{nt}

A = 5,500,000.00(1 + 0.04/4)^{(4)(5)}

A = 5,500,000.00(1 + 0.01)^{20}

A = $6,711,045.22

Hence, The total amount accrued is $6,711,045.22.

Mr.jacobs budgeted $1,200 for tiles. His sketch of the floor requires him to use 38 white tile. each white tile cost $12. Write
Arturiano [62]
Given: 
Budget for tiles = 1,200
number of white tiles = 38
unit cost of white tiles = 12
budget for brown tiles = x

cost of white tiles = 38 x 12 = 456

The inequality would be:

Cost of brown tiles + cost of white tiles <u><</u> budget
x + 456 <u><</u> 1,200

solving the inequality:
x + 456  <u><</u> 1,200
<u>   - 456        -456</u>
x      <u><</u> 744

Mr. Jacobs can spend up to 744 for the brown tiles.

Separate the number 219 into three parts. The second number is two less than 5 times the first number, and the third number is 4
Sav [38]
Let us assume the first number = x
Then the second number = 5x -2
The third number = x + 4
The total number that needs to be divided into three parts is 219
Then we can write the equation as
x + 5x - 2 + x + 4 = 219
7x + 2 = 219
7x = 219 - 2
7x = 217
x = 217/7
  = 31
Then
First number = 31
Second number = 5x - 2
                           = (5 * 31) - 2
                           = 155 -2
                          = 153
Third number = x + 4
                       = 31 + 4
                       = 35
So the three numbers are 31, 153 and 35.

Tanisha solved the equation below by graphing a system of equations. log3 5x = log5 ( 2x + 8). What system of equations could be
Marta_Voda [28]

Answer:

The set

y=log_3 (5x)

y=log_5 (2x+3)

Step-by-step explanation:

We separate the left and right side of the equation, to create two new equations:

(1) y=log_3 (5x)

(2). y=log_5 (2x+3)

and then to solve Tanisha's original equation, we find the solution to the system that we got above.

The first step in solving the above system of equations is to take the value for y from equation(1), and substitute it into equation(2) which gives us:

y=log_5 (2x+3)\\\\ \boxed{log_3(5x) = log_5 (2x+3)}

which is the same equation that Tanisha set out to solve.
