The unit price of the sodas is $1.25. It would cost $312.5 for 250
If you are asking for a common factor of 16 AND 20 the answer can be 80
Hope this helped :)
Answer:
graph your y intercept at negative 8 and then continue to go up one right one
Each game costs 1.25 and each ride costs 3.75
Step-by-step explanation:
Let,
Cost of each game = x
Cost of each ride = y
According to given statement;
5x+6y=28.75 Eqn 1
4x+3y=16.25 Eqn 2
Multiplying Eqn 2 by 2
![2(4x+3y=16.25)\\8x+6y=32.50\ \ \ Eqn\ 3](https://tex.z-dn.net/?f=2%284x%2B3y%3D16.25%29%5C%5C8x%2B6y%3D32.50%5C%20%5C%20%5C%20Eqn%5C%203)
Subtracting Eqn 1 from Eqn 3
![(8x+6y)-(5x+6y)=32.50-28.75\\8x+6y-5x-6y=3.75\\3x=3.75](https://tex.z-dn.net/?f=%288x%2B6y%29-%285x%2B6y%29%3D32.50-28.75%5C%5C8x%2B6y-5x-6y%3D3.75%5C%5C3x%3D3.75)
Dividing both sides by 3
![\frac{3x}{3}=\frac{3.75}{3}\\x=1.25](https://tex.z-dn.net/?f=%5Cfrac%7B3x%7D%7B3%7D%3D%5Cfrac%7B3.75%7D%7B3%7D%5C%5Cx%3D1.25)
Putting x=1.25 in Eqn 1
![5(1.25)+6y=28.75\\6.25+6y=28.75\\6y=28.75-6.25\\6y=22.50](https://tex.z-dn.net/?f=5%281.25%29%2B6y%3D28.75%5C%5C6.25%2B6y%3D28.75%5C%5C6y%3D28.75-6.25%5C%5C6y%3D22.50)
Dividing both sides by 6
![\frac{6y}{6}=\frac{22.50}{6}\\y=3.75](https://tex.z-dn.net/?f=%5Cfrac%7B6y%7D%7B6%7D%3D%5Cfrac%7B22.50%7D%7B6%7D%5C%5Cy%3D3.75)
Each game costs 1.25 and each ride costs 3.75
