Paul organised an event for a charity. Each ticket for the event cost £19.95
Paul sold 395 tickets.

Paul paid costs of £6000
He gave all money left to the charity

Work out the an estimate for the amount of money Paul gave to the charity?

The answer is 2000. Hope this helps! If I could have brainliest I'm trying to rank up :)

Step-by-step explanation:

This question asks us to estimate the amount of money Paul gave to Charity.  

To work out an estimate we must start by rounding the numbers we are given to 1 significant figure and the

Starting with 19.95 --> this rounds to 20 and 395 rounds to 400.  

Then we have to multiply these numbers together:

20 x 400 = 8000

3. Finally subtract 6000 from our estimate

8000-6000=2000

The answer is 2000.

let's add {f(x)=x+1}f(x)=x+1 and {g(x)=2x}g(x)=2x together to make a new function.

f(x)+g(x) =(x+1)+(2x)=x+1+2x=3x+1

let's call this new function hh. so we have:

{h(x)}={f(x)}+{g(x)}{=3x+1}h(x)=f(x)+g(x)=3x+1

we can also evaluate combined functions for particular inputs. let's evaluate function hh above for x=2x=2. below are two ways of doing this.

method 1: substitute x=2x=2 into the combined function hh.

h(x)

h(2)

​    

=3x+1

=3(2)+1

=7

​ since h(x)=f(x)+g(x)h(x)=f(x)+g(x), we can also find h(2)h(2) by finding f(2) +g(2)f(2)+g(2).

first, let's find f(2)f(2):

f(x)

f(2)

​    

=x+1

=2+1

=3

​  

now, let's find g(2)g(2):

g(x)

g(2)

​    

=2x

=2⋅2

=4

​  

so f(2)+g(2)=3+4=\greend7f(2)+g(2)=3+4=7.

notice that substituting x =2x=2 directly into function hh and finding f(2) + g(2)f(2)+g(2) gave us the same answer!
