Tickets for Adults were $14.50 and tickets for Children were $9.00. We purchased 12 tickets and spent a total of $135.50 to get
into the aquarium. How many adult tickets and student tickets did we purchase?
2 answers:
children tickets = 7
adult tickets = 5
a+c=135.5
14.5+c=135.5
14.5x7=72.5
135.5-72.5= 63
c=63
Answer:
(5 , 7)
Step-by-step explanation:
let a = the number of adult tickets
let c = the number of children tickets
then we have to solve the following system
a + c = 12
14.5a + 9c = 135.5
we proceed by Substitution:
c = 12 - a
14.5a + 9c = 135.5
After some calculations we find
a=5 and c=7
