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%
Answer:
Basic fee = $14.95
1.5 dollars per quart of oil
Step-by-step explanation:
Each customer is charged a fee x (in dollars) for the oil change, plus y dollars per quart of oil used.
The oil change for the car that requires 5 quart of oil costs $22.45.
The oil change for the car that requires 7 quarts of oil costs $25.45.
Both equation having x
so make it equal and solve for y
Add 7y on both sides
subtract 22.45 from both sides
now plug in 1.5 for y and solve for x
Horizontal shift 1 unit left and vertical shift 11 units up

x=√(36)
x=6
