Question

Hayley and alex are counting their pocket money. hayley has three times as much money as alex. together they have £20 in total. how much money do they each have?

Answer 1

Alex's money = x
Hayley's money = 3x (she has three times as much money as him)

20 = x + 3x
20 = 4x
/4      /4
5   =  x

So Alex's money = 5. Hayley's money is 3 times his, so Hayley's money is 15.
