City leaders estimate that the current population of a city is 9.72 × 105 people. They predict that the population will increase by 1.1 × 104 people each year over the next decade. According to their prediction, which is the best estimate for the city's population in 4 years?
A.
10.16 × 1010 people
B.
1.412 × 106 people
C.
1.016 × 106 people
D.
1.412 × 1011 people
The best estimate for the city's population in 4 years can be calculated by multiplying the population increase per year by 4 and adding it to the current population.
1.1 × 104 people increase per year * 4 years = 4.4 × 104 people
9.72 × 105 people + 4.4 × 104 people = 1.016 × 106 people
Therefore, the best estimate for the city's population in 4 years is C. 1.016 × 106 people.
