Пошаговое объяснение:

Если у мамы не хватает 100 рублей на 6 кг фруктов,а на 4 кг фруктов у неё останится 60 руб.То мы можем узнать сколько стоят два кг.

1) 6-4=2(кг)-на столько больше.

2)100-60=40(руб.)-2 кг

Теперь сколько стоит 1 кг.

3)40:2=20(руб.)-1 кг

Узнаём сколько денег у мамы.

4) 20*4=80(руб.)-4 кг

5)  80+60=140(руб.)

Ответ: у мамы 140 рублей, 1 кг фруктов стоит 20 рублей.

Удачи!

(100+60):(6-4)=80 (руб)- 1кг

80*4+60=380 (руб)-всего у мамы

Answer 3

#### Calculation of the Amount of Money Mama Has To calculate the amount of money Mama has, we can set up a system of equations based on the given information. Let's assume the cost of 1 kg of fruit is **x** rubles. According to the problem, if Mama buys 6 kg of fruit, she will be short of 100 rubles. This can be represented as the equation: **6x - 100 = 0** Similarly, if Mama buys 4 kg of fruit, she will have 60 rubles left. This can be represented as the equation: **4x - 60 = 0** To find the amount of money Mama has, we need to solve these two equations simultaneously. #### Solving the Equations Let's solve the system of equations using the substitution method. From the first equation, we can express **x** in terms of **6**: **6x = 100** **x = 100/6** Simplifying, we get: **x = 16.67** Now, we can substitute this value of **x** into the second equation: **4(16.67) - 60 = 0** Simplifying, we get: **66.68 - 60 = 0** **6.68 = 0** Therefore, the second equation is not satisfied. This means there is no solution to the system of equations. #### Conclusion Based on the given information, there seems to be an inconsistency in the problem. The system of equations does not have a solution, which means we cannot determine the amount of money Mama has or the cost of 1 kg of fruit. Please double-check the information provided or provide additional details if available.
