Answer:

<em>1 pound of apple costs $2.50</em>

<em>1 pound of strawberries costs $1.25</em>

Step-by-step explanation:

<u>System of Equations</u>

Let's define the following variables:

x = cost of 1 pound of apples

y = cost of 1 pound of strawberries

.........................................

Marcus purchased 3 pounds of apples and 4 pounds of strawberries for a total of $12.50. Thus:

3x + 4y = 12.50       [1]

Shannon purchased 5 pounds of apples and 1 pound of strawberries for a total of $13.75, thus:

5x + y = 13.75       [2]

We need to solve the system of the equations [1] and [2].

Solving for y in [2]:

y = 13.75 - 5x       [3]

Substituting in [1]

3x + 4(13.75 - 5x) = 12.50

Operating:

3x + 55 - 20x = 12.50

-17x = -55 + 12.50 = -42.50

Dividing by -17:

x = -42.50/(-17)

x = 2.5

Substituting in [3]:

y = 13.75 - 5*2.5

y = 1.25

Solution:

1 pound of apple costs $2.50

1 pound of strawberries costs $1.25

Mean: The average or the center of the value. To find this, you add up all the numbers and divide by how many numbers there are. 
Example: 3, 4, 5
3+4+5 = 12. 
There are 3 numbers.

12/3 = 4. The mean is 4

Median: Median means the middle value. You place the numbers in order and locate the middle value. 

Example: 5, 4, 3 -> 3,/ 4,/ 5. Middle number 4.

Mode: Place the numbers in order then count how much each number appears. The number that appears the most repeatedly would be the mode.

Example: 3, 4, 4, 4, 5, 5. 

The mode would be 4.

Range: Locate the highest and the lowest values of the given set and subtract the smallest to the largest.
