A tea shop offers tea in cups of three different sizes. The product of...
Let's rephrase the given information and calculations:
Assuming we have three cup sizes: Small, Medium, and Large, Let the price of a Small cup be 2x. Let the price of a Medium cup be 5x. Let the price of a Large cup be Ax.
According to the given information, The product of the prices (2x * 5x * Ax) equals 800.
After a price increase, The new product of the prices ((2x + 6) * (5x + 6) * Ax) equals 3200.
By dividing both of these equations, we find: (10x2 + 42x + 36) / (40x2) = 1.
Simplifying the equation gives us: 30x2 - 42x - 36 = 0.
Further simplification leads to: 5x2 - 7x - 6 = 0.
Factoring the equation, we get: (5x + 3)(x - 2) = 0.
Therefore, x = 2.
Now, we can determine the prices for each cup size: Small cup price = 4. Medium cup price = 10. Large cup price = 20 (as the product is 800).
To find the sum of the original unit prices, we add: Small price + Medium price + Large price = 4 + 10 + 20 = 34.
