Ward Fineman had a $4,090.75 average monthly expenditure for travel during the second quarter of the year. He spent $6,150.00 in July and $3,250.00 in August. How much can Ward spend in September to have the same average as in the second quarter?

Answer 1

$4090.75 is the average of 3 months (the second quarter). The question wants you to give what you would spend in September to get the same average. Because average is:

total expenditures
------------------------
total number of expenditures

And you know the total number, you just need to figure out what the top is.

6150.00 + 3250.00 + September
---------------------------- = 4090.75
number of months
