max number of candies
orangefronted   5
N 2 hours ago by EthanNg6
A store sells a strawberry flavoured candy for 1 dollar each. The store offers a promo where every 4 candy wrappers can be exchanged for one candy. If there is no limit to how many times you can exchange candy wrappers for candies, what is the maximum number of candies I can obtain with 100 dollars?

two solutions
τρικλινο   10
N 2 hours ago by τρικλινο
in a book:CORE MATHS for A-LEVEL ON PAGE 41 i found the following


1st solution


$x^2-5x=0$



$ x(x-5)=0$



hence x=0 or x=5



2nd solution



$x^2-5x=0$

$x-5=0$ dividing by x



hence the solution x=0 has been lost



is the above correct?

I didn't have enough time to finish the sprint :mad: I heard that the later questions were all quite simple though. Predicting 27+16=43 as my score.

Yeah, the sprint was about chapter level. Unfortunately, I didn't get target #6, my friend got 2024. What did you guys get for target #8?

My favorite problems on the state test were target #6 and sprint #29. I loved the aha moment when I saw pascal's triangle on target #6, and even though I got sprint #29 wrong due to a long division error, it was so much fun to use the sum of the factors trick to find the right answer!
Also: My score was 29 with 12 on target and 17 (sad sillies) on sprint, so I didn't make CDR :(
