Calculating the Total Cost of the Meal

To calculate the total cost of the meal, we can use the given menu prices for the 7 types of dishes and 11 types of drinks. Let's denote the total amount spent by the group as I.

The menu prices are as follows: - Hamburger: 500 tg - Doner: 250 tg - Kefir: 800 tg - Cola: 400 tg - Pizza: 1200 tg - Water: 150 tg - Toast: 500 tg - Fanta: 400 tg

Using the given information, we can calculate the total cost of the meal by summing the products of the quantity of each item purchased and its respective price.

Calculation

The total cost I can be calculated using the following formula: I = (500x1) + (250x1) + (800x1) + (400x1) + (1200x1) + (150x1) + (500x1) + (400x1) + (500x1) + (400x1) + (400x1)

Total Cost

By substituting the given prices and quantities into the formula, we get: I = 500 + 250 + 800 + 400 + 1200 + 150 + 500 + 400 + 500 + 400 + 400 = 5700 tg

Therefore, the group could have spent 5700 tenge using the given menu prices.
