4 0

New number - original number

561,000 - 438,000 = 123,000.

Increased number divided by the original number

123,000 ÷ 438,000 = 0.28

Multiply by 100

0.28 x 100 = 28%

The percentage increase would be 28%

Answer:

  $13,916.24

Step-by-step explanation:

First, we need to find the value of the CD at maturity.

  A = P(1 +rt) . . . . simple interest rate r for t years

  A = $2500(1 +0.085·3) = $2500×1.255 = $3137.50

__

Now, we can find the value of the account with compound interest.

  A = P(1 +r)^t . . . . . rate r compounded annually for t years

  A = $3137.50 × 1.18^9 = $13,916.24

The mutual fund was worth $13,916.24 after 9 years.

Shalnov [3]



Let

x ------> number of switch type A

y -----> number of switch type B

so

Remember that

1 hour=60 min

32 hours=32*60=1,920 minutes

4x+5y=1,920 -------> equation 1

3x+5y=1,740 ------> equation 2

Solve the system of equations

Solve by graphing

using a graphing tool

see the attached figure

Solution is

x=180

y=240

therefore

<h2>the number of switch type A was 180</h2><h2>the number of switch type B was 240</h2>
