Question 111

A bacteria culture starts with 500 cells and grows by 10% each hour for 2 hours. Enter the final number of cells.

Correct answer

605

Explanation

Repeated growth uses the updated amount each hour, so 500 × 1.10 × 1.10 = 605. Adding two lots of 10% of the original would give 600 and would model simple growth instead.
