2d+7-7=9-7

The equation now looks like this:

2d=2

Divide 2 on both sides:

2d/2=2/2

The cost of every college is expected to increase 3.5%
next year.
The cost to attend Faber College is currently $24000.
If the percentage increase stays constant, what will the
cost be in TWO years?

Answers

Answer:

25,709.4

Step-by-step explanation:

First you would multiply 3.5 x 24,000, and then divide by 100, to get 840, and then add that to the original  amount to get 24,840, and that is the cost for one year. And then you would multiply 24,840 by 3.5 and then divide by 100 to get 869.4. Finally just add that to 24,840 to get 25,709.4, and that is the cost for 2 years. I hope this helps :)

The cost of college in two years is $25709.4.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Cost of Faber college  = $24000

Rate of increase = 3.5%

The cost of college after one year.

= 103.5% of 24,000

= 103.5/100 x 24000

= $24,840

The cost of their college after two years.

= 103.5% of 24,000

= 103.5/100 x 24,840

= $25709.4

Thus,

The cost of college in two years is $25709.4.

Autumn invested $69,000 in an account paying an interest rate of 6 3/8% compounded continuously. Jayden invested $69,000 in an account paying an interest rate of 6 1/4% compounded quarterly. After 14 years, how much more money would Autumn have in her account than Jayden, to the nearest dollar?

Answers

Answer:

4,038.21

Step-by-step explanation:

I'm going to assume that when you write 6 3/8% that equals 51/8%=6.375%

To find the value in the first equation we have

69000*e^(.06375*14)=168,444.5313

The second equation is as follows

69000(1+(.0625/4))^(14*4)=164,406.3243

Subtract the two and get 4,038.2071

What percent of 60 is 45?

Answers

over all answerrr 75

The percentage is 75%, the amount is 45 and the base is 60 so option (D) will be correct.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.

Given that 45 is some percentage of 60

So, 60 will be the base because we are calculating the percentage of it and the amount will be 45.

Let's say 45 is x percentage of 60

Then,

60 × x/100 = 45

x = 4500/60

x = 75%

Percentage will be 75

Hence "The percentage is 75%, the amount is 45 and the base is 60".
