Calculating the Cost of Purchases in a Self-Service Store

To calculate the cost of the purchases made by the customers in a self-service store, we need to multiply the quantity of each item by its respective price and then sum up the total cost.

Let's calculate the cost for each customer:

1. First customer: - 2 packs of milk at 19 rubles each: 2 * 19 = 38 rubles. - 1 pack of butter at 17 rubles: 1 * 17 = 17 rubles. - 3 packs of kefir at 14 rubles each: 3 * 14 = 42 rubles. - Total cost for the first customer: 38 + 17 + 42 = 97 rubles.

2. Second customer: - 1 pack of milk at 19 rubles: 1 * 19 = 19 rubles. - 3 packs of butter at 17 rubles each: 3 * 17 = 51 rubles. - 3 packs of kefir at 14 rubles each: 3 * 14 = 42 rubles. - Total cost for the second customer: 19 + 51 + 42 = 112 rubles.

Now, let's determine if the customers have enough money to pay for their purchases:

- The first customer has a total cost of 97 rubles, which is less than 100 rubles. So, the first customer has enough money to pay for their purchases. - The second customer has a total cost of 112 rubles, which is more than 100 rubles. So, the second customer does not have enough money to pay for their purchases.

Therefore, the first customer has enough money to pay for their purchases, but the second customer does not have enough money.
