Question 288385: 1. This coming summer, we are meeting up with some other family members at Family Fiesta Amusement Park. The ticket price for children is $17 and for adults the ticket price is $31. The total price for all 20 of us to enter the park is $438.
a. Write an equation, using A for adults and C for children, that illustrates the number of tickets bought.
Answer by jaydducote(11) (Show Source): You can put this solution on YOUR website!
A is adult tickets, which cost 31
C is children tickets, which cost 17
we know 20 people are going, all are either adults or children
we know the total price is 438
if 20 people go and they are all adults or children, then A+C=20 <----- this is A
Since we know the tickets add up to a total, we know that 31A+17C=438 <----- this is B
Those are the two equations that you need to solve the problem. You have to have both, so I'm not sure how else to "Write an equation, using A for adults and C for children, that illustrates the number of tickets bought." You need two equations, then you can use substitution or something to solve them.
