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

a) Gavin’s drinks altogether cost £9.00
1.50+2.50x3
=1.50+7.50
=£9.00
b) Lian gets back £3.50
1.50+2.00+3.00
=6.50

10.00-6.50=£3.50

Answer 2

a) The total cost of Gavin's drinks is £10.00. b) Lian should receive £3.50 in change.

Step-by-step explanation:

a) Gavin pays for one extra small drink and three large drinks. To find the total cost, we add the cost of each drink. The extra small drink costs £1.00.

Each large drink costs £3.00. Adding these values together, the total cost is £1.00 + (£3.00 * 3) = £1.00 + £9.00 = £10.00.

b) Lian pays for one small drink, one medium drink, and one extra large drink. To find the total cost, we add the cost of each drink. The small drink costs £1.50. The medium drink costs £2.00.

The extra large drink costs £3.00. Adding these values together, the total cost is £1.50 + £2.00 + £3.00 = £6.50.
