Answer 1

Answer:

Adult = 700

Children = 300

a = Adult

c = Children

Then- a + c

= 1000 ---------------------------(1)

8.50

a + 4.50

c = 7300 -----------(2)

Solve the equation (1) for c

c = 1000 − a

Substitute the value of c in equation (2)

8.50

a + 4.50 ( 1000 − a ) = 7300

8.50

a + 4500
