Answer 1

Population after one year​ is 1070

Step-by-step explanation:

given data

population = 1000

Birth rate = 10%

annual death rate = 3%

solution

we get here annual increase rate that is

annual increase rate =  10% - 3%

annual increase rate   = 7%

we use her formula that is

A = P × $(1+\frac{r}{100})^t$     ................1

put here value

A = 1000 × $(1+\frac{7}{100})^1$  

A = 1070

so population after one year​ is 1070
