Question

Poppy, felix and alexi sell 700 raffle tickets between them. Poppy sells twice as many tickets as felix, and alexi sells 25 mor tickets tan poppy. How many tickets did each of them sell.

Answer 1

p = # of tickets that Poppy sold
f = # of tickets that Felix sold
a = # of tickets that Alexi sold

p + f + a = 700 (first part)
2f = p (second part)
p + 25 = a (third part)

(2f) + 25 = a (substitution)
(2f) + f + (2f + 25) = 700 (more substitution)
5f + 25 = 700
5f = 675
f = 135

2(135) = p (plug it in)
p = 270

270 + 25 = a (plug it in again)
a = 295

Felix: 135 tickets
Poppy: 270 tickets
Alexi: 295 tickets

Hope this helps. :)
