Answer:
Front section tickets: $40
Back section tickets: $25
Step-by-step explanation:
If x is the price of back section tickets, and x + 15 is the price of front section tickets, then:
275 (x + 15) + 325 x = 19125
275 x + 4125 + 325 x = 19125
600 x = 15000
x = 25
So back section tickets are $25, meaning front section tickets are $40.

Set up a proportion to solve.
(4mg/5ml)= (20mg/x ml)
Be sure you line up the mg to mg and the ml to ml.
Notice I have both mg on the numerator and both ml on the denominator.
To solve you need to cross multiply.
4x = 5(20)
4x = 100
divide by 4
x = 25 ml
