Question

U 3 4

Answer 1

Answer: 50%

Step-by-step explanation:

I'm converting 7kg to grams to make it easier. So £10 = 7000g

£1 = 7000÷10 = 700g

700g÷2 = 350g and if you follow the ratios on top, she payed 50p per 350g

She sells a bag of 350g for 75p.

Percentage profit=$\frac{Change in cost}{original cost}$ × 100

75p - 50p = 25p = change in cost

Percentage profit= $\frac{25}{50}$ × 100

= 50%
