Always use the formula that I gave you:
\[\frac{ greater - lesser }{ actual } \times 100\]

- calculusxy

The only "tricky" part here is that they just said "sold 114 raffle tickets at $5 each for the fundraiser, actually earning for the fundraiser." So that leaves you to find the actual price. This shouldn't be too hard because you just multiply: 114 times $5 and get your answer

bro
just do 114 times 5

- calculusxy

1. 114 x 5 = ?
2. \[\frac{ $500 - ($14 \times 5) }{ ($14 \times 5) } \times 100\]

- calculusxy

I have tried to make it as simple as I could.

-614.2857 is this right @calculusxy

- anonymous

Ok how many tickets did she sell times the price per ticket?

- anonymous

57,000

- anonymous

No, that's not it.

- anonymous

570

- anonymous

Ok that's it. Now what was the original prediction?

- anonymous

$500

- anonymous

Now the person before get how their equation works?

- anonymous

what do you meen

- anonymous

I'll show it.
\[\frac{ 500 - (14 x 5) }{ (14 x 5) } x 100\]
Make any sense?
Remember PEMDAS?

Hold on, I don't think thats right.

- anonymous

Perenthesis first, its
\[\frac{ 500 x 70 }{ 70 }\]

- anonymous

500 times 70 is 35,000.
What did you do next?

- anonymous

fraction or divition

- anonymous

I think it's divison.
Correct? @calculusxy

- anonymous

500

- anonymous

Ok I re-did this.
Do 112.3% 500 and it's about 561.
So what you did was wrong.
I'll try to explain this.
You got the 114 being 570, the expected was 500.
What is the difference?

- anonymous

70

- anonymous

Divide it by 5. What do you get?

- anonymous

14

- anonymous

Ok, 500 is 100%,
Add the 14%
114%
What's 114% of 500?

- anonymous

14%

- anonymous

right?

- anonymous

No, 114%.
Do 500 times 1.14
What is the result?

- anonymous

570

- anonymous

Ok then what is the answer to the question?

- anonymous

C

- anonymous

There you go. If you medal, medal the other guy.

- Bella2112

i understood nothing

- anonymous

lol

xD

- Bella2112

i kept reading it and i still didnt understand

- anonymous

It's pretty easy to do, just gotta find the overestimate or underestimate difference.
Multiple the 114, you get 570.
Take the 570 and the 500. Find the difference. 70.
The 70 divide by 5 is 14.
As the 570 is above the original estimated it makes it a over percentage.
Aka 114%
On a calc it's 1.14.

what do you mean by xD
