Question

Lottie buys a pack of 50 cans of lemonade.

Answer 1

Answer:

15.3%

In Order:

1) Lotte buys 50 cans for £17.

2) Sells 32 cans for 50 penny each.

3) Sells remaining for 20 penny each.

Solve:

Total cost for 32 cans:

price of each can × total cans

50 penny × 32

1600 penny

Remaining Cans : 50 - 32 = 18 cans

Total cost of this 18 cans:

20 penny × 18

360 penny

$\boxed{\bf 100 \ penny \ (p) = 1 \ pound \ ( \sf \£ )}$

Total Gained : 1600 + 360 = 1960 pence ≈ £19.6

Profit : selling price - cost price : 19.6 - 17 = £2.6

Profit In percentage:

$\sf \dfrac{(selling \ price - cost \ price)\ x \ 100}{cost \ price}$

$\rightarrow \sf \dfrac{2.6\ x \ 100}{17}$

$\rightarrow \sf 15.294 \%$

$\rightarrow \sf 15.3 \% \ \ (rounded \ to \ nearest \ three \ significant \ figure)$

Answer 2

Answer:

£15.7

Step-by-step explanation:

32 cans x 50P = 1600p

1600p to Pounds = £26.66 (1600 divided by 60)

Remaining cans = 18 (50 - 32)

18 cans x 20p = 360p

360p to Pounds = £6 (360 divided by 60)

£26.66 + £6 = £32.66

£32.66 (Profit) - £17 (Cost of cans) = £15.66

15.66 to 3SF = 15.7
