Answer:

$25.00

Step-by-step explanation:

You already know that $85 is an additional fee added to the monthly fees.

So, you first have to subtract 85 from $685 to get the total amount of monthly fees paid over 2 years.

685-85= 600

So, you can conclude that $600 is the total amount of monthly fees paid.

Now, you want to divide 600 by (the number of months in 2 years) to get the amount of monthly fees.

Since there is 24 months in 2 years you do:

600/ 24 which equals 25.

In conclusion, you can find that the monthly fee is $25.00.

Suppose the scores of seven members of a women’s golf team are 68, 62, 60, 64, 70, 66, and 72. Find the mean, median, and midran
grin007 [14]
Mean - add up all of the scores, and divide it by the number of members:

68 + 62 + 60 + 64 + 70 + 66 + 72 = 462
462 / 7 = 66

ANSWER: The mean is 66

Median - write out all the numbers in order, and select the middle value:

60, 62, 64, 66, 68, 70, 72

ANSWER: As you can see, 66 is the middle value.

Midrange - find the mean (average) of the smallest and largest number:

Largest number: 72
Smallest number: 60

Midrange:   72 + 60 = 132
                     132 / 2 = 66

ANSWER: So the midrange is 66
