Question

В первом мотке 88 м проволоки, а во втором - 150 м такой же проволоки. За первый моток заплатили на 2 руб. меньше, чем за второй. Какова стоимость двух мотков проволоки?

Answer 1

150-88=62 м - разница в длине

За 62 м заплатили 2 р

Значит 1м=2/62=1/31 руб

88*1/31=2,83 руб

150*1/31=4,83 руб

2,83+4,83=7,66 руб - стоимость двух мотков

Answer 2

Calculating the Cost of Wire

To calculate the cost of the two wire spools, we can use the information provided.

Given: - Length of wire in the first spool = 88 m - Length of wire in the second spool = 150 m - Cost difference between the two spools = 2 rubles

We can calculate the cost of the wire using the following steps:

1. Calculate the Cost per Meter for Each Spool: - Let's assume the cost per meter of wire in the first spool is x rubles. - The cost per meter of wire in the second spool would then be (x + 2) rubles.

2. Calculate the Total Cost for Each Spool: - Total cost for the first spool = (88 * x) rubles - Total cost for the second spool = (150 * (x + 2)) rubles

3. Equating the Total Costs: - We know that the total cost for the first spool is 2 rubles less than the total cost for the second spool.

4. Solving for x: - We can solve for x to find the cost per meter of wire in the first spool.

5. Calculating the Total Cost of Both Spools: - Once we have the cost per meter for the first spool, we can calculate the total cost for both spools.

Let's proceed with the calculations.
