A soccer team ordered 12 jerseys and 12 pairs of shorts, for a total of $156. Later, they had to order 4 more jerseys and 6 more pairs of shorts, for a total of $62.

Jersey cost $8 and pair of shorts $5

Step-by-step explanation:

There are several ways to solve this, but I will find the solution using the system of equations.

Let's mark price of jersey with x, and price of pair of shorts with y. That means:

12x + 12y = 156

4x + 6y = 62

Now, we can multiply the second equation with -2 to cancel out y:

12x + 12y = 156

-8x - 12y = -124

That only leaves us with:

12x - 8x = 156 - 124

4x = 32

x = $8

Now we plug the value for x into any equation to find y:

4x + 6y = 62

32 + 6y = 62

6y = 30

y = $5

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
