Answer 1

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

Answer 2

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

Answer 16

Now the person before get how their equation works?

Answer 17

what do you meen

I'll show it.

\[\frac{ 500 - (14 x 5) }{ (14 x 5) } x 100\]

Make any sense?

Remember PEMDAS?

Answer 20

Hold on, I don't think thats right.

Answer 21

Perenthesis first, its

\[\frac{ 500 x 70 }{ 70 }\]

Answer 22

500 times 70 is 35,000.

What did you do next?

Answer 23

fraction or divition

Answer 24

I think it's divison.

Correct? @calculusxy

Answer 25

500

Answer 26

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?

Answer 27

70

Answer 28

Divide it by 5. What do you get?

Answer 29

14

Answer 30

Ok, 500 is 100%,

Add the 14%

114%

What's 114% of 500?

Answer 31

14%

Answer 32

right?

Answer 33

No, 114%.

Do 500 times 1.14

What is the result?

Answer 34

570

Answer 35

Ok then what is the answer to the question?

Answer 36

C

Answer 37

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

Answer 38

thank you

Answer 39

Your welcome.

Stay frosty,

Answer 40

ok

Answer 41

i understood nothing

Answer 42

lol

Answer 43

xD

Answer 44

i kept reading it and i still didnt understand

Answer 45

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.

Answer 46

what do you mean by xD
