The number of fish in a lake decreased by 25% between last year and this year. Last year there were 60 fish in the lake. What is the population this year?

The population this year is 35

Step-by-step explanation:

We are given the information that , the fish population decreased by 25% last year and this year meaning that in all it decreased by 50%. And last year it was 60 fish meaning that this year, it will be decreased by 50% . If is being decreased by 50% , 50% will be left.

So multiply 50% by 60 to find the population this year.

60 * 75% =

60 * 0.75 = 30

45 fish

Step-by-step explanation:

To find the answer you would first convert the percentage into a decimal which would be 25% for this problem. Then you multiply the original price by the decimal. 60 x 0.25=15. Next you would subtract the discount from the original price which would be 60-15=45.
