Your answer is 4 radical 2.
Answer: 985 g
Step-by-step explanation:
Total mass = 8 × 500g = 4000g
Let the three new packs be X, Y, and Z, for first, second, and third pack respectively.
4000g = X + Y + Z
let's put X and Z in terms of Y, since we're trying to solve for the second pack.
X = 2Y, and Z = Y + 60
Therefore,
4000 = X + Y + Z
4000 = 2Y + Y +Y + 60
4000 = 4Y +60
4000 - 60 = 4Y
3940 = 4Y
3940 ÷ 4 = Y
985g = Y = mass of the second pack

The non cash price of the car before discount is £8000.
What is discount?
The discount is determined by dividing the purchase price by the item's par value. Discount is a type of cost price reduction or deduction for a product. It is primarily employed in consumer interactions when discounts on various goods are offered to customers. A percentage represents the discount rate.
Here Discount rate = 15%
Car price after discount = £6800
Here we know that before discount car price is 100%.
Then, after discount car price will be (100%-15%)=85%
Here , 85%= 6800
Then, 100%=x
=> x = 
=> x = £8000.
The non cash price of the car is £8000.
