1) The price of a computer is reduced by 5%. The actual reduction is $17.
Find the original price of the computer.

2) Peter borrows $5000 from a bank at a rate of 9.2% per year compound interest. Calculate the amount he owes after 2 years. Give you answer to 2 decimal places.

Please I really need help!

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, 9% is two-hundredth, which means 9%=9/100=0.09.

The percentage is just like the amount of that value but in between 1 to 100 and it is very useful to predict for example if you say 541 then we have to know about the full number also but if you say70% then it becomes clear.

The price of the computer let's say x than

[( change in price)/(original price)] × 100 = 5%

[( $17 )/(original price)] × 100 = 5%

Original price = $340. hence, it will correct the answer

Principle amount $5000

Rate of interest 9.2%

Time period 2 years

Interest after 1 year = $460

Principle amount after one year become $5000+$460 = $5460

Interest after 2 years will become = $502.32

Principle amount after the second year become

$5460 + $503.32 = $5962.32 will be correct answer.
