Q. The population of a city decreases by 3% per year. If this year's population is p, which expression represents next year's population?p−0.031p−0.03p3p0.97
Identify percentage decrease: The question prompt is: "What expression represents next year's population if the current population is p and it decreases by 3% per year?"
Convert to decimal: Identify the percentage decrease in the population.The population decreases by 3% each year.
Calculate decrease: Convert the percentage decrease to a decimal.3% as a decimal is 0.03.
Subtract from current population: Calculate the decrease in population.The decrease in population is 3% of p, which is 0.03×p.
Simplify expression: Subtract the decrease from the current population to find next year's population.Next year's population is p−(0.03×p).
Simplify expression: Subtract the decrease from the current population to find next year's population.Next year's population is p−(0.03×p). Simplify the expression.Next year's population is p−0.03p, which simplifies to 0.97p.
