The number 450 is increased by 75%. The result is then decreased by 90%. What is the final number?

Answers

Answer:

The final number is 78.75

Step-by-step explanation:

we know that

1) The number 450 is increased by 75%

The number 450 represent 100%

Remember that

$100\%+75\%=175\%=175/100=1.75$

The increased number is

$450(1.75)=787.5$

2) The result is then decreased by 90%

In this moment

787.5 represent the 100%

Remember that

$100\%-90\%=10\%=10/100=0.10$

The decreased number is

$787.5(0.10)= 78.75$

therefore

The final number is 78.75

A sequence is defined recursively by f(0)=2 and f(n)=f(n+1)=-2f(n)+3 for n greater than or equal to 0, then f(2) is equal to

Answers

If you would like to know what is f(2), you can calculate this using the following steps:

f(0) = 2
f(n+1) = - 2 * f(n) + 3
f(1) = - 2 * f(0) + 3 = - 2 * 2 + 3 = - 4 + 3 = - 1
f(2) = - 2 * f(1) + 3 = - 2 * (-1) + 3 = 2 + 3 = 5

The correct result would be f(2) = 5.
