The total admission price for a group of 3 adults and 7 children is $41.

To find:

The admission prices for an adult and for a children.

Solution:

Let the price of an adult be x and price of children be y.

According to the question,

        ...(i)

     ...(ii)

Multiply equation (i) by 3.

        ...(iii)

Multiply equation (i) by 4.

     ...(iv)

Subtract (iv) from (iii).

Divide both sides by 2.

Put y=3.5 in (i).

Divide both sides by 4.

Therefore, the price for an adult is $5.5 and price for a child is $3.5.
