Problem Analysis

Kolya bought 5 cans of condensed milk and gave the cashier 100 rubles, receiving 15 rubles in change. We need to find the price of one can of condensed milk.

Solution

To find the price of one can of condensed milk, we can subtract the change received from the amount given to the cashier and divide the result by the number of cans purchased.

Let's calculate it step by step:

1. Amount given to the cashier: 100 rubles. 2. Change received: 15 rubles. 3. Amount spent on condensed milk: 100 rubles - 15 rubles = 85 rubles. 4. Number of cans purchased: 5 cans. 5. Price of one can of condensed milk: 85 rubles / 5 cans = 17 rubles per can.

Therefore, one can of condensed milk costs 17 rubles.

Conclusion

Kolya bought 5 cans of condensed milk for a total of 85 rubles, which means that one can of condensed milk costs 17 rubles.
