5. Kathy plans to purchase a car that depreciates (loses value) at a rate of 14% per
year. The initial cost of the car is $21,000.
How much will the car be worth
in 6 years?

At the end of the 1st year you have 21,000-0.14(21000)

= (1-0.14)21000 = 0.86(21,000)

So after three years you have 21000(0.86)(0.86)(0.86)

= 21000(0.86)^3

3360

Step-by-step explanation:

Find 14% of 21,000 then multiply by six which gives you 17,640. Then you subtract 21,000-17640. that is your answer.

60

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
