Answer:
1. 50 = 5x+15
2. 50 = 3x+20
3. 7
4. 10
5. Skating Rink
Step-by-step explanation:
1. As the maximum amount of money is 50 dollars, you are given that there is a 5 dollar entry *per* person, alongside the 15 room rental fee added on. That is where the equation 5x+15 = 50 comes from
2. The same can be said with the skating rink, with different numbers. 3 *per* person plus the extra 20 room rental fee.
3. 50 = 5x+15 can be solved by subtracting 15 by both sides. This gives us 35=5x and dividing by 5 will give us 7 = x
4. 50 = 3x+20 can be solved by subtracting 20 by both sides. This gives us 30=3x and dividing by 3 will give us 10 = x
5. As 10>7, it's apparent that you can bring more people to the Skating Rink
