Question

В магазин прислали 3 коробки с бананами. В первой коробке было 40 бананов, во второй 71. Вторая коробка оказалась на 620 руб. дороже первой. Сколько стоит 1 банан? Сколько стоят обе коробки?

Answer 1

71-40=31б- на столько больше во второй коробке

620/31=20руб- стоит 1 банан

40+71=111б- в двух коробках

111*20= 2220руб- стоят две коробки

Answer 2

х-стоимость банана

71х-40х=620

31х=620

х=20

итак,один банан стоит 20рублей,тогда две коробки стоят 40*20+71*20=800+1420=2220 рублей

ответ 20рублей. 2220 рублей

 

 

Answer 3

Calculation of Banana Prices and Total Cost

To calculate the price of one banana and the total cost of both boxes, we can use the information provided:

- The first box contains 40 bananas. - The second box contains 71 bananas. - The second box is 620 rubles more expensive than the first box.

Let's calculate the price of one banana and the total cost of both boxes step by step:

1. Calculate the price of one banana in the first box: - Let's assume the price of one banana in the first box is x rubles. - The total cost of bananas in the first box would be 40 * x rubles.

2. Calculate the price of one banana in the second box: - Since the second box is 620 rubles more expensive than the first box, the price of one banana in the second box would be x + 620 rubles. - The total cost of bananas in the second box would be 71 * (x + 620) rubles.

3. Set up an equation to solve for x: - The total cost of bananas in the first box plus the total cost of bananas in the second box should equal the total cost of both boxes. - So, we have the equation: 40 * x + 71 * (x + 620) = Total cost of both boxes.

4. Solve the equation to find the value of x: - By solving the equation, we can find the value of x, which represents the price of one banana.

Let's calculate the price of one banana and the total cost of both boxes using the given information.
