Hello there! So, the room is $40 to rent, and it costs $12 per person. To solve this, we can write and solve an equation. Set it up like this:

40 + 12g = 100

This is because Milli has $100 to spend. $40 is the fixed cost and the $12 goes up based in the number of guests. Let’s start off by subtracting 40 from both sides. 40 - 40 cancels out. 100 - 40 is 60. That leaves us with 12g = 60. Now, divide each side by 12 to isolate the g. 12g/12 cancels our. 60/12 is 5. There. g = 5. Milli can invite 5 guests to her party.
