Answer:
Adult is 200$ and children is 375$
Explanation:
I. The clues we got are total tickets and total price.
adult price is 1.5$ and children price is 1$
Given a = adult and c = children
a + c = 575 => {total tickets}
1.5a + 1c = 675 => {total price}
II. Find a and c values by eliminate a or c
{total price} - {total tickes} will return to
(1.5a - 1a) + (1c - 1c) = 675 - 575
0.5a = 100
a = 200
III. Replace a value in {total tickets} will return to
200 + c = 575
c = 375
IV. Prove by replace a and c value in {total price}
200(1.5) + 375(1) = 675
300 + 375 = 675 true
That makes adult ticket is 200 and children ticket is 375.
Hope that help :)
