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

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

529 and 531
