Given the following set of expenses: $7,

Answer:

a. 16.50-6.50= $10.00

b. 16.50+6.50/2= 11.50

c. 16.50+7+12+6.50+10/5= 10.40

These are the correct answers.

Answer:

See below in bold.

Step-by-step explanation:

Greatest = $16.50, least = $6.50

a. Difference is $10.

b. Mean of greatest and least is  (16.50 + 6.50 ) / 2 = $12.50.

c. Mean of the data set = (7 + 16.50 + 12 + 6.50 + 10) /  5 = 52/5

= $10.40.
