the stem - and - leaf plot below gives the amount of money spent by each of\namount of money spent (in dollars)\n3|0 4 9\n4|0 4 5 6 9 9\n5|0 0 1 6 8\n6|2 3\nkey: 3|0 means 30 dollars.\n(a) how many couples spent an amount in the 60s?\n(b) what was the least amount spent overall?\n(c) what was the greatest amount spent in the 50s?

Answer

Explanation:

Step1: Count values in 60s

In the stem - and - leaf plot, the stem value of 6 has 2 leaf values (2 and 3). So the number of values in the 60s is 2.

Step2: Find least value

The lowest stem value is 3, and the lowest leaf value for the stem of 3 is 0. So the least amount spent overall is 30.

Step3: Find greatest value in 50s

The stem value is 5. The greatest leaf value for the stem of 5 is 8. So the greatest amount spent in the 50s is 58.

Answer:

(a) 2 (b) 30 (c) 58
