Answer:

an = 7 + 5n

Step-by-step explanation:

First we know that for each number of days rented the cost increase by 5 so we get an - (?) + 5n.

We also know the first number is 12 for 1 day, so for 0 days, or the starter cost, is 7. We get this by subtracting 5 from 12.

Hence the answer an = 7 + 5n

If 10% of all machines become worthless every year (they depreciate, in other words), then how many machines will become worthle
nikklg [1K]

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.

X = 360 - 130 - 134 = 96
