Question

The total airfare of a family of 2 adults and 3 children was 5600 how much was each child's airfare if it was half the adult fare

Answer 1

Let fare for children be x
So fare for afults will be 2x
Equation = 4x + 3x = 5600
=>7x = 5600
=> x = 5600 / 7
=> x = 800
So fare for children is 800 Rs
Adult fare is 1600 Rs

Answer 2

let the air fare of an adult is x

and the fair of 1 children be y

x=2y

therefore 2(2y)+3y

=4y+3y

=7y

5600=7y

5600/7=y

y=800

therefore each child's fare is 800
