A sofa depreciates at 20% of its original value each year. If the sofa was $349 at its time of purchase, what is the value of th

klemol [59]

Answer:

$142.95

Step-by-step explanation:

Given Original value of the sofa = $349

Rate of depreciation each year = 20%

Number of years = 4

To find the value of the sofa after 4 years use depreciation formula:

If the constant decrease in population be R% per annum. Then the population after n years is $P \times\left(1-\frac{R}{100}\right)^{n}$

$349 \times\left(1-\frac{20}{100}\right)^{4}=349 \times\left(\frac{100-20}{100}\right)^{4}$

$=349 \times\left(\frac{80}{100}\right)^{4}$

$=349 \times\left(\frac{4}{5}\right)^{4}$

= 142.9504

= 142.95 (Nearest cent)

Hence, the value of sofa after 4 years is $142.95.

Twice the sum of a number and 77 is equal to three times the difference of the number and 6. Find the number

tino4ka555 [31]

x + 77 = 3(x - 6)

x + 77 = 3x - 18

x + 77 + 18 = 3x - 18 + 18

x + 95 = 3x

x + 95 - x = 3x - x

95 = 2x

x = 95/2

x = 47.5
