Charlie recieved some pocket money,
he used 1/5 of it on shopping,
he used 3/4 to buy a ticket to the cinema.

he was left with £3.80

how much money did charlie start with?

either 76 or 19

Step-by-step explanation:

76 if it's 1/5 of the original amount as well as 3/4 the original amount

1/5+3/4=19/20

3.80=1/20x

3.80+19/20x=76

3.8*20=76

19 if it's 1/5 of the original amount and 3/4 of the new amount

3.80=1/4y

3.80+3/4y=15.20

15.20=4/5x

15.20+1/5x=19
