Adult ticket to a museum costs $3 more than a children's ticket. When 200 adult tickets
100 children's tickets are sold, the total revenue is $2100. What is the cost of a
Children's ticket?

Answer 1

Explanation:

a = adult cost

c = child cost

a = c + $3

200a + 100c =$2100

^ each # of tickets sold

200(c+3) + 100c =$2100

200c + 600 + 100 c = 2100 combine like terms

300c + 600 = 2100 need variable only on one side of equal sign so you subtract 600 from each side of the = sign

300c = 1500 now divide by 300 on both sides to isolate variable

c = $5
