Answer:
x=20
y=?
Step-by-step explanation:
The curve passes through y-axis at
Substituting
into
we have:
The y-intercept is -24
Call u the cost per uniform.
Since each of the 15 players gets one uniform and one basketball, we can make the following equation:
15u + 15(9) = 420
Solve this equation to get u=285/15= $19
Here are my answers to the given questions above:
Part 1. Here is my example of a real life scenario that describes what is happening. Let us say, I have 2 cookies and the bottle of milk costs 11 dollars, and 3 cookies and 4 bottles of milk cost 24 dollars.
Part 2.
y=11-2x
3x+4(11-2x)=24
3x+44-8x=24
-5x=-20
x=4
y=11-8
y=3
Therefore, each cookie costs 4 dollars, and a bottle of milk costs 3 dollars.
Hope this answer helps. Let me know if you need more help next time.
