Answer:
The mom ate 49 fish.
Step-by-step explanation:
This question can be solved by a rule of three.
a mother otter is fed 7 fish for every 2 fish for its cub
if a cub has eaten 14 fish , how many fish did the mother eat ?
For each 2 fish cub eats, the mon eats 7. How much has the mom eaten if the cub has eaten 14?
So
2 - 7
14 - x
2x = 14*7
Simplifying by 2
x = 7*7
x = 49
The mom ate 49 fish.
So it starts with 12 in the bacterial population. After 1 hour, 6 are added. After another hour passed, 9 are added. 12/1, 18/6, 27/9.
The equation would be ' y = 1/2x'
