290d + 245
Hello! So what you do first is make two equations, then combine them.
For the food booths, the equation would be 15(4d) + 150
For the game booths, the equation would be 23(10d) + 95
Now simplify them.
Food booths: 60d + 150
Game booths: 230d + 95
Next, we combine the two equations to get one equation.
60d + 150 + 230d +95
Simplify even more...
This is going to be your equation. I don't know the number of days the fair went so I can't go any futher on this question. Hope this helps though!
Answer: 3 and -7
