Answer: 10 or 6 I believe
Step-by-step explanation:
1.5*10=15
2.5*6=15
A graphing calculator shows it has 3 real solutions, near x ∈ {-3.033, 1.241, 2.964}.
Let give Poppy = P, Felix = F, Alexi = A
so P+ F + A = 700 ----(1)
P = 2F ----(2)
A = 25 + P ---(3)
we will think in term of P
from (2) F = P/2
from (1) P + F + A = 700
P + P/2 + 25 + P = 700 ---(4)
(4) multiplied by 2
2P + P + 50 + 2P = 1400
5P + 50 = 1400
5P = 1350
so P = 270
so Poppy sold 270 tickets
Felix sold 135 tickets
and Alexi sold 295 tickets //
2 - 125x = 0,5x - 5
-125x - 0,5x = -5 -2
-125,5x=-7
x= -7/-125,5
x=0,05...
If A is the buying value & B the selling value, then the increase =
Increase = (B-A)/A = (1.15 - 0.87)/0.87 = 0.3218 or 31.18%
