Answer:
the common ratio is 0.98.
Step-by-step explanation:
A fish population in a lake decreases by 2% each year. We are asked to find the common ratio.
The decrease of population of fish 2% annually means the population becomes next year 100% - 2% = 98%
Therefore, the common ratio would be 98%. Upon converting 98 percent to a decimal we will get,
98% =
Therefore, the common ratio or decay factor is 0.98.
We can write it down like this:
4%*x=56
where we want to find the x
first, i would change the % into fraction.
multiply both sides by 100
divide by four:
and that's our answer, 1400!
