Let A= adult tickets and S= student tickets
A+S=148
9A+6S=1,188
You can plug into a calculator or by hand is shown below
-6(A+S)=-6(148) Checking the answer
-6A-6S=-888 A=100
+ 100+S=148
9A+6S=1,188 S=48
——————— 9(100)+6(S)=1,188
3A+0S=300 900+6S=1,188
1/3(3A)=1/3(300) 6S=288
A=100 S=48
And to check is on the right side
Make a proportion to get the answer the proportion will be

to give you the answer of 37.5
Answer:
Daniel must tutor 160 hours
Explanation:
310+275+70= 655
655×6= 3930 (he needs this amount of $)
(Daniel gains $20 per hour)
20×160= 3200
3200+745= 3945
3945 > 3930
Daniel has enough for the trip.
Where did I get 160?
Well, I was just trying out numbers and multiplying it by 20
The numbers I tried: 100, 150, 156, 159 & 160 but only 160 fit with the answer.
If it was just one night road trip he would've just needed $655, but since it's a 6-night road trip I multiplied it by 6.
Hope this helped!
