Answer:
The selling price of meter of cable must be equal to 3 euros
Step-by-step explanation:
The question in English is
A hardware store buys 4 reels of cable of 200 meters each at 2 euros per meter. How much must the meter sell if you want to earn 800 euros?
we know that
The profit will be equal to the selling price minus the purchase price, all multiplied by the total meters of cable
Let
x -----> the selling price of the meter of cable
y -----> the purchase price of the meter of cable
N ----> the meters of cable
P ----> the profit
so
we have
The total meters of cable N purchased is equal to
substitute
Solve for x
Simplify
therefore
The selling price of meter of cable must be equal to 3 euros
Answer:
542, 543, 544, 545.
Step-by-step explanation:
Divide 2174 by 4 = 543.5
(because there are 4 integers) 543.5 is not an integer.
However, one of the four integers is 543.
Write down four consecutive numbers that include 543 and add them:
like 541+542+543+544 =. if that is 2174, you have the answer, if it's too low, try moving up one number, like
542+543+544+545 = if it's still too low, move up one number again
543+544+545+546=
You only have to do that a max of 3 times to get the answer.
The four consecutive integers are
542, 543, 544, 545.
