Question

A scientist is studying a population of 1,000 geese. One year ago, 400 of the geese were male. Now, after several births and deaths among the population, the number of males in the goose population is 500. Assuming the total population is still 1,000, how much more of the population is male compared with one year ago?

Answer 1

The male goose population has increased by 10% from last year, going from 400 out of 1000 (40%) to 500 out of 1000 (50%).

Step-by-step explanation:

The student's question involves a basic percentage calculation in Mathematics, aimed at understanding population changes in geese. Initially, there were 400 male geese out of 1000, which means 40% of the population were male. Now, there are 500 males out of 1000, indicating 50% of the population are male.

To calculate this difference in percentage terms, you subtract the initial percentage of males (40%) from the current percentage (50%) to find the increase: 50% (current percentage of males) - 40% (previous percentage of males) = 10% increase. The question asks how much more of the population is male compared to one year ago. To find the difference, we need to subtract the number of males one year ago from the current number of males. One year ago, there were 400 male geese, and now there are 500 male geese. So, the difference is 500 - 400 = 100.
