Calculation of the Total Cost of Vegetables

To calculate the total cost of the vegetables, we need to determine the cost of the potatoes and the proportion of the potatoes' cost to the total cost of the vegetables.

Given information: - The cafeteria purchased 7 bags of potatoes at a price of 450 rubles per bag. - The cost of the potatoes represents one-fifth (1/5) of the total cost of the vegetables.

To find the total cost of the vegetables, we can follow these steps:

1. Calculate the cost of the potatoes: - Number of bags of potatoes: 7 - Price per bag of potatoes: 450 rubles - Cost of the potatoes = Number of bags * Price per bag = 7 * 450 = 3150 rubles.

2. Calculate the total cost of the vegetables: - Since the cost of the potatoes represents one-fifth (1/5) of the total cost of the vegetables, we can use the proportion to find the total cost. - Let's assume the total cost of the vegetables is represented by "x" rubles. - The cost of the potatoes is one-fifth of the total cost: (1/5) * x = 3150 rubles. - Solving for "x", we can multiply both sides of the equation by 5: x = 5 * 3150 = 15750 rubles.

Therefore, the total cost of all the vegetables is 15750 rubles.
