To find the mean you have to get the average number found by adding all data points and dividing by the number of data points.

Example: The mean of 4, 1, and 7 is (4+1+7)/3 = 12/3 = 4

For median you have to get the middle number which is found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).

Example: The median of 4, 1, and 7 is 4
because when the numbers are put in order (1, 4, 7) the number 4 is in the middle.

To get the mode you have to get the most frequent number which is, the number that occurs the highest number of times.

Example: The mode of {4,2,4,3,2,2} is 2 because it occurs three times, which is more than any other number.

Hope that helps.

A cashier has 26 bills consisting of three times as many ones as fives, one less ten than fives, and the rest twenties. If the v
monitta
Let number of  fives = x then number of ones = 3x  and number of tens = x - 1

so we can create the equation 

x + 3x +  x-1 + y = 26  where y = number of twenties
so
5x + y = 27

also we have the equation 

5x + 3x + 10(x - 1) + 20y = 120

18x + 20y = 130..................................(1)
5x    + y    = 27     multiply  by -20:-
-100x - 20y = -540..............................(2)
Adding equation (1) and (2)
-82x = -410
x  = 5,  that is  5 fives

Now plug x = 5 into equation 1:-
18(5) + 20y = 130
20y =  40
y =  2 ,   that is 2 twenties

So the answer is   there are (3x) = 15 ones , 5  fives, 4 tens and 2 twenties
