Answer:
x=5 and x=15
Step-by-step explanation:
3x^2-60x+225=0
3x^2-60x+225/3=0/3
x^2-20x+75=0
x^2-5x-15x+75=0
x(x-5)-15(x-5)=0
(x-5)(x-15)=0
x-5=0 x-15=0
x=5 x=15
3/10 is 30%
30% + 17% = 47%
100% is our total animals
100% - 47% (Lions + Zebras) = 53% (Tigers)
So 53% are tigers.
55% of 100 is 55
55+100=155
Selling price: $155
No problem! :)
