2a+3c=56, a+4c=49.50
2a+3c=56.00
-2(a+4c=49.50)
_______________
2z+3c=56
-2a-8c=99
____________
0+-5c=-43
-5c=-43
c= -43/-5
child ticket=8.60
now take c and plug the answer into the first equation: 2a+3c=56, 2z+3(8.60)=56, 2z+25.80=56, 2a=56-25.80, 2a= 30.20, a=30.20/2, adult tickets =15.10
Ratio=4.0 *10⁷ Krill / day
amount of krill=ratio * days
amount of krill=(4.0*10⁷ Krill /day)(3.65*10² days)=1.46*10¹⁰ krill
Answer: 1.46*10¹⁰ krill
Answer:
