Answer:
The second option
Explanation:
Let's see if we can solve each one and find out which is better. We shall start with the first option.
If the cost is $30 per person, and you and 9 of you are going, that makes 10.
30x10 is the same as $300. So let's note that down; $300 for the first option.
Let's move onto the next option. Your friends are considered a group, so whatever the price is you add 50 to it.
If the cost is $20 per person, and again 10 of you are going, then:
$20 x 10 is the same as 200.
But remember, the group fee is $50, so we need to add that.
200+50 = 250.
So comparing, 300 is $50 greater than 250. So the best deal is the second option.
