Ok, so I can't work out the answer to this question for my maths homework and I need some help please! So here it is:
It is £1.50 to park a car in a car park.
This can be paid in £1 coins or 50p coins.
In one day, the car park collected 136 £1 coins and 208 50p coins.
How many drivers paid with three 50p coins?
