Joey opened a bank account 5 years ago with $100. today he has $1000 in the account. what is the percentage od increase?

anyanavicka [17]

To calculate the percentage increase:

First: Find out the difference (increase) between the two numbers you are comparing.
It is computed by: Increase = New Number - Original Number

Second: Divide the increase by the original number and multiply the answer by 100.
It is computed by: % increase = Increase ÷ Original Number × 100.

So in the problem:
First step:Increase = 1000 – 100
Increase = 900

Second:
% increase = 900 / 100 x 100%
increase = 900% increase

9. All the students in the sixth grade either walk home or take the bus home after scho

timurjin [86]

There are 250 students in sixth grade

Solution:

Given that, All the students in the sixth grade either walk home or take the bus home after school

From given,

Number of students walk home = 170

Let "x" be the total number of students in school

32% of the students take the bus

Thus, 32 % of "x" takes bus

To find: total number of students in school

Total students = Number of students walk home + number of students takes bus

$x = 170 + 32 \% \times x\\\\x = 170 + \frac{32}{100} \times x\\\\x = 170 + 0.32x\\\\x - 0.32x = 170\\\\0.68x = 170\\\\x = 250$

Thus there are 250 students in sixth grade
