Question

In a family 3 adults and 2 children visit a play park for a total cost of $1100 and 2 adults and 3 children from another family visit the same play park for the total cost of Rs. $900. Find the cost of the ticket for each adult and each child, the play park charges.

Answer 1

Answer:

lets take the number of adults as a and children as c

3a+2c=1100

2a+3c=900

using substitution method

2c=1100-3a

c=1100-3a

        2

2a+3c=900

but c =1100-3a

                2

2a+3[1100/2-3a/2]=900

2a+3300/2-9a/2=900

2a-9/2a=900-3300

-5/2a=-2400

a=-2400x-2/5

adults=Rs 960

c=1100/2-3a/2

but a=960

children=-2330

1100/2-3/2[960]

1100/2-1440

children=2880
