Question 27 of 49intermediate🔧 ApplyLong Answer5 marks

The initial population of a village is 750. Every year, 50 people move from a nearby city to the village.

(i)

Find the population of the village after 6 years.

(ii)

Make a table of values for tt varying from 0 to 10 years and show how the population, PP, increases every year.

(iii)

Find an expression that relates PP and tt, and explain why it represents linear growth.

Explanation

The problem involves calculating linear growth based on a constant rate of change. The initial value is 750 and the constant increase is 50 per year.

For part (i), we multiply the rate by 6 years and add it to the initial value. For part (ii), we generate values by repeatedly adding 50. For part (iii), we formulate the linear equation P=750+50tP = 750 + 50t and justify it using the textbook's definition of a linear relationship (y=ax+by = ax + b) and the constant difference between consecutive terms.
