Answer 3

Question Analysis

The user is asking if their mother, who has 5 banknotes worth 10 rubles each and one banknote worth 100 rubles, can buy 4 packets of juice for 25 rubles each and 3 packets of milk for 20 rubles each.

Answer

To determine if the mother can buy the desired items with the given amount of money, we need to calculate the total cost of the items and compare it to the total amount of money she has.

Calculation

The cost of 4 packets of juice at 25 rubles each is 4 * 25 = 100 rubles. The cost of 3 packets of milk at 20 rubles each is 3 * 20 = 60 rubles.

Therefore, the total cost of the items is 100 rubles + 60 rubles = 160 rubles.

Comparison

The mother has 5 banknotes worth 10 rubles each, which is a total of 5 * 10 = 50 rubles. She also has one banknote worth 100 rubles.

Therefore, the total amount of money she has is 50 rubles + 100 rubles = 150 rubles.

Conclusion

The total cost of the desired items is 160 rubles, while the mother only has 150 rubles. Therefore, she does not have enough money to buy 4 packets of juice for 25 rubles each and 3 packets of milk for 20 rubles each.

The mother cannot buy 4 packets of juice and 3 packets of milk with the given amount of money.
