316,800 inches that is the correct answer
Answer: Country A - 10machines
Country A - 1,000machines
Country A - 10,000machine
step-by-step explanation:
Since 10℅ of all machines becomes worthless every year, let's look at each country.
If 100 machines are all the machines in country A, then 10% of all the machines in country A (i.e 100 machines) will be 10% of 100 = 10 machines.
Similarly for country B, it will be equivalent to 10% of 10000, which is equal to 1,000machines.
Same goes for country C i.e 10% of 1000000 = 10,000machines are worthless.
The first thing to do is to clear the equation of fractions by multiplying by its LCM, which is 6 in this case. When you do that, you will get the equation
4p + 36 = 7p. Much easier to deal with, right? Now move the 4p over by subrtracting it: 36 = 3p, and p = 12
