Answer:
Let the price of one senior citizen ticket be <em>sc</em> and the price of one student ticket be <em>st</em>.
Let's write equations using the information given and the variables above:
=> 5sc + 15st = $137.50
=> 20sc + 44st = $430
Hmm.. We can multiply 5sc by 4 to get 20sc.
=> 4(5sc) + 4(15st) = 4($137.50)
=> 20sc + 60st = $550
Now we can subtract the second equation from the first to determine the price of a student ticket.
20sc + 60st = $550
- 20sc + 44st = $430
=> 16st = $120
=> st = $7.5
So, the price of a student ticket is $7.5.
I'm pretty sure the answer would be D... A triangle has three angles, and three sides. it already has to angles used and one left I guess...
