Answer:
Berta can invite 16 people.
Step-by-step explanation:
1. Take the total money that Berta has.
$100
2. As the room rental cost is $50, subtract this quantity from the total money that Berta has:
$100 - $50 = $50
3. Take the remaining $50 and divide them between the cost per additional person to find the number of people that Berta can invite to her party:
[tex]\frac{50}{3}=16[/tex]
Therefore Berta can invite 16 people to her party and $2 dollars left over.
