Step2: Count values in the 60s

Look at the 6 - stem. The leaves on the 6 - stem are 1, 4, 5, 6. So there are 4 couples who spent an amount in the 60s.

Step3: Find the greatest value in the 50s

The 5 - stem has leaves 3, 4, 5, 6, 8, 9. The greatest leaf on the 5 - stem is 9. So the greatest amount spent in the 50s is 59 dollars.
