a) Gavin pays for one extra small and three large drinks.
Altogether, how much did they cost?
b) Lian pays for one small, one medium and one extra large drink.
She pays with a £10 note.
How much change should she get?

Answer 1

for A. Gavin would pay 10. because 1.00 + 3.00 + 3.00 + 3.00 is 10.
and for B. 1.50 + 2.00 + 3.00 = 6.50. so lian would get 3.50 change back.
