Jeffs trip will cost $9 if he has 2 attendees at the conference. If there are 36 attendees, how much will the trip cost Jeff

Respuesta :

We need to set up a proportion. 

9/2 = x/36

x is the amount that we need to find for. We need to solve for x so we can figure out the answer.

9/2 = x/36

First, we cross multiply

9*36 = 2x
324 = 2x

Next, we divide each side by 2.

2x/2 = 324/2

The 2's cross out.

x= 324/2
x= 162

Our final answer is that it will cost Jeff $162 if he has 36 attendees at the conference. 

Hope I helped! :D

if its $9 for two people then that mean it costs $4.50 for one person so just multiply 36 times $4.50 which is $162 . hope i helped
