Best ResponseYou've already chosen the best response.2Always use the formula that I gave you: \[\frac{ greater  lesser }{ actual } \times 100\]

Best ResponseYou've already chosen the best response.2The 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

Best ResponseYou've already chosen the best response.21. 114 x 5 = ? 2. \[\frac{ $500  ($14 \times 5) }{ ($14 \times 5) } \times 100\]

Best ResponseYou've already chosen the best response.0I'll show it. \[\frac{ 500  (14 x 5) }{ (14 x 5) } x 100\] Make any sense? Remember PEMDAS?

Best ResponseYou've already chosen the best response.0Ok I redid 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?

Best ResponseYou've already chosen the best response.0Ok, 500 is 100%, Add the 14% 114% What's 114% of 500?

Best ResponseYou've already chosen the best response.0It'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.
