Step-by-step explanation:£23.25 are left after he has purchased his snack pack. because game tickets cost £0.50 , all you have to do is times 0.5 by the numbers given (46,48,23,75 ) until you get past the money limit which is £23.25
all i did was 46 x 0.5 which was £23
if i were to do 48 x 0.5 the answer i would get is £24, however, as you can see the amount of money greg has left is £23.25, which means 48 tickets is out of his budget
