Question

Four friends buy cinema tickets using this offer. Cinema tickets buy 3 tickets and get a ticket free they each pay £6.15 how much does a ticket cost?

Answer 1

The cost of one ticket will be  £8.20

Explanation

Suppose, the cost of one ticket is $x$

As the offer says "buy 3 tickets and get a ticket free" , it means they actually need to pay for 3 tickets.

So, the total cost of 3 tickets $=3x$

Each of four friends pay £6.15 , so the total amount they pay $=\£6.15 *4 = \£24.60$

Thus, the equation will be .....

$3x=24.60\\ \\ x=\frac{24.60}{3}=8.20$

So, the cost of one ticket will be  £8.20
