Tickets at an amusement park are $25 for children and $45 for adults. If the Jones family has $200 cash and they have two children, what is the maximum amount of adult tickets they can purchase?

3 maximum adult tickets

Step-by-step explanation:

children's ticket = $25

adult's ticket = $45

total amount of money $200

let x be the number of adults:

45x + 2(25) = 200

45x + 50 = 200

45x + 50 - 50 = 200 - 50

45x = 150

x = 3

to check:

2 children x $25 each = $50 in total

4 adults x $45 adults = $135 in total

⇒ $200 - ($135 + $50)

⇒ $200 - $185  

⇒ $15 remaining

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
