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= × 100
75p - 50p = 25p = change in cost
Percentage profit= × 100
= 50%
The scale factor is 1/3 because 9 x 1/3 = 3 and 6 x 1/3 = 2.
Answer:
z=66
