"a rise of a quarter from  last year" means the percentage went up by 25%

x = old value

x + 25% of x = x + 0.25x = 1.25x = new value = 0.25 since "1 in 4" means 1/4 = 0.25

So,

1.25x = 0.25

x = 0.25/1.25

x = 0.2

x = 2/10

x = 1/5

Answer:  The fraction of families that owed money is 1/5, or 1 in 5.

A construction company plans to invest in a building project. There is a 30% chance that the company will lose $30,000, a 40% ch
Gnom [1K]

Answer: Option 'A' is correct.

Step-by-step explanation:

Since we have given that

30% chance that the company will lose $30000.

40% chance of a break even that there is no loss and no profit.

30% chance that the company will profit $ 60000.

As we know the formula for "Expectation":

So, Expected value will be

\frac{30}{100}\times (-30000)+\frac{40}{100}\times 0+\frac{30}{100}\times 60000\\\\=03\times (-30000)+0.4\times 0+0.3\times 60000\\\\=-9000+18000\\\\=\$9000

Expected value is $9000. So, the company should proceed with the project.

Hence, Option 'A' is correct.
