Explanation:
Consider the provided information.
The games you can play at the Amusement Park average $5 per game and your ticket was $50. Your cost for the day is $100.
You have $100 and your ticket was $50.
So now you have:
.
That means after buying ticket you are left with $50.
Let n represents the number of games and you can play average $5 per game.
Therefore, for n number of games you need to pay
![5n](https://img.qammunity.org/2020/formulas/mathematics/middle-school/kjb5uq7gfr3stiki87s2g1gz11lw94quav.png)
You have $50 left and you need to pay
per game, So the distance C remaining after you pay n games is:
![C=50-5n](https://img.qammunity.org/2020/formulas/mathematics/middle-school/t0sx3judufeci9mxwd6icwdzaudguf6s50.png)
Hence, the required equation is
