Question

Last year the population of Spoon Forks grew from 1250 to 1300. If the population of the town grows by the same percent this year, what will the population be? (7.RP.3)

Answer 1

1352

Explanation:

Firstly, we get the percentage growth last year. This is calculated as:

(1300-1250)/1250 * 100

= 4%

Now, we are assuming the growth rate is constant. So let’s calculate a 4% growth rate for this year. That would be:

4/100 * 1,300 = 52

The population this year would thus be 1300 + 52 = 1352
