Lets solve this step by step.
8 * 8 = 64
Lets suppose there are 8 aquariums and there are 8 fish in each. Therefore, there are 8 groups of 8 fish. Add and solve.
8+8+8+8+8+8+8+8 = 64
Answer:
y = 314
Step-by-step explanation:
y = 650 - 16x
y = 650 - 16(21)
y = 650 - 336
y = 314
1/4 = 0.25
5/8 = 0.625
20% = 0.20
So now we have: 0.20 < 0.25 < 0.3 < 0.625 < 0.85
So the solution is 20%, 1/4, 0.3, 5/8, 0.85
A is the answer because it is the widest variety
