3 0

Answer:

k= -0.2

Step-by-step explanation:

3+2(5k-3)=7 (original)

3+10k-6=7 (distribute 2 in (5k-3))

9+10k=7 (combine like terms 3+-6)

10k=-2 (subtract 9 on both sides to isolate k)

k=-0.2 (divide 10 on both sides to get you're answer/isolate k)

today a boat valued at $45,000.Thebvalue is expected to decrease at a rate of 8.5% each year.What is the value of the boat expec

Stels [109]

Current value of the boat = $45000

Rate at which the value decrease = 8.5%

Value decreased after 1 year = $\frac{8.5}{100}\times45000=3825$

Hence, value becomes = $45000-3825=41175$

Value decreased after 2nd year =

$\frac{8.5}{100}\times41175=3499.875$

Hence, value becomes = $41175-3499.875=37675.125$

Value decreased after 3 year =

$\frac{8.5}{100}\times37675.125=3202.385$

Hence, value becomes = $37675.125-3202.385=34472.74$

So, value of the boat after 3 years becomes $34472.74
