Question 10 • APSB 2025 Math Essentials-ALP

The value of a collector’s item is expected to increase exponentially each year. The item is purchased for $500 and its value increases at a rate of 5% per year. Find the value of the item after 4 years.

Answer
A
$578.81
B
$607.75
C
$1687.50
D
$2531.25

Explanation

For exponential growth, multiply the starting value by (1 + the annual rate) for each year: $500 × 1.05⁴ = $607.753125. Rounded to the nearest cent, the item will be worth $607.75 after 4 years, which is choice B.
