Calculation of the Cost of a Coffee Cup

To calculate the cost of a coffee cup, we need to consider the information provided. In one day, the store sold 6 tea cups at a price of 100 rubles each and 10 coffee cups. The total revenue from all the cups sold was 1,800 rubles.

Let's assume the cost of each coffee cup is x rubles.

The revenue from the tea cups can be calculated as follows: 6 tea cups * 100 rubles = 600 rubles.

The revenue from the coffee cups can be calculated as follows: 10 coffee cups * x rubles = 10x rubles.

The total revenue from all the cups sold is given as 1,800 rubles.

Therefore, the equation can be set up as follows: 600 rubles + 10x rubles = 1,800 rubles.

To find the value of x, we can solve the equation:

600 rubles + 10x rubles = 1,800 rubles.

Subtracting 600 rubles from both sides of the equation, we get:

10x rubles = 1,200 rubles.

Dividing both sides of the equation by 10, we get:

x = 120 rubles.

Therefore, the cost of each coffee cup is 120 rubles.

Please note that the calculation assumes that the revenue from the tea cups is separate from the revenue from the coffee cups. If the revenue from all the cups sold is combined, the calculation may be different.
