Question

Berta is planning a party for her friends. The room rental cost is $50 plus an additional $3 per person to cover food costs. Berta has saved up $100 dollars. What is the maximum number of people that can attend her party?

Answer 1

The correct answer is 16

Answer 2

Berta can invite 16 people.

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:

`(50)/(3)=16`

Therefore Berta can invite 16 people to her party and $2 dollars left over.
