Respuesta :
The price of a child ticket is $9.84 and an adult ticket is $11.17
Answer:
The cost of child ticket is $9.3.
The cost of adult ticket is $10.6.
Step-by-step explanation:
Given : The price for an adult movie ticket it [tex]1\frac{1}{3}[/tex] more than a movie ticket for a child. Ines takes her daughter to the movie, buys a box of popcorn for $5.50 and spends $26.50.
To find : Write and solve an equation to find prices for each of their movie tickets ?
Solution :
Let the price of one child ticket be 'x'.
The price for an adult movie ticket it [tex]1\frac{1}{3}=\frac{4}{3}[/tex] more than a movie ticket for a child.
i.e. The price for adult ticket is [tex]x+\frac{4}{3}[/tex]
She buys a box of popcorn for $5.50.
Total cost of tickets and popcorn is [tex]x+\frac{4}{3}+x+5.50[/tex]
Total she spends is $26.50.
So, [tex]x+\frac{4}{3}+x+5.50=25.50[/tex]
[tex]2x=25.50-5.50-\frac{4}{3}[/tex]
[tex]2x=20-\frac{4}{3}[/tex]
[tex]2x=\frac{60-4}{3}[/tex]
[tex]2x=\frac{56}{3}[/tex]
[tex]x=\frac{56}{3\times 2}[/tex]
[tex]x=\frac{28}{3}[/tex]
[tex]x=9.3[/tex]
The cost of child ticket is $9.3.
The cost of adult ticket is [tex]x+\frac{4}{3}=\frac{28}{3}+\frac{4}{3}=\frac{32}{3}=10.6[/tex]
The cost of adult ticket is $10.6.
