Question

Fargo is doing an intensive swim program over the summer holidays.

In his first session, he swims 50 laps.

In his second session, he swims 10% more laps than his first session.

In his third session, he swims 20% more laps than his second session.

How many laps does Fargo swim at his third practice?

Worked Solution

1st session = 50 laps
2nd session = 50 + (10% × 50)
= 50 + 5
= 55 laps

3rd session = 55 + (20% × 55)
= 55 + 11
= 66 laps
