Question

the diagram shows the price paid by two groups of people visiting a fair. assume that each adult pays the same price and each child pays the same price

Answer 1

Let, price paid by adults be x and children be y.

then,

5x+4y=78----(1)

3x+6y=63----(2)

Solving both we get

x=12,y=4.5

So adult pays £12 and child pays £4.5
