There are 9 people going on a trip. They purchased coach tickets for $160, and first class tickets for $1180. The total budget to spend was $4500. How many first class tickets did they buy? How many Coach tickets did they buy? Show your work.
Answer:
Step-by-step explanation:
Given
There are 9 people going on a trip
They purchased coach tickets =$160
first class tickets =$1180
total budget to spend = $4500
Let coach tickets=X
So first class tickets=9-x
160x+1180(9-x)=4500
160+10620-1180x=4500
160x-1180x=4500-10620
-1020x=-6120
X=6120/1020
X=6
So answer
Coach tickets=X=6
First class tickets=(9-x)
=3.

x + 2x = 108
Step-by-step explanation:
Let x be the number of oranges sold on Thursday
The number of oranges sold on Friday is twice as many or 2 times x, 2x
