140 for 4
150 for 6

how much for each guest
what's the equation for the total cost for the party
how much for 15 people and the party room ​

Answer 1

Explanation:

I skipped the answer line because they are pasted below.

Since there is a ten dollar difference for two people, each guest is 5 dollars. If each guest is 5 dollars, the party room is 120. If we want to create an equation, we have:

y=5x(each guest is 5 dollars)+120(the basic fee).

If we use 15 here, we have that it will be $195.

ANSWERS DOWN HERE:

1. $120

2. $5

3. y=5x+120

4. $195
