Don bought his car for $20,350. it is expected to depreciate an average of 11% each year during the first 5 years.
what will the approximate value of his car be in in 5 years?

The approximate value of Don car be in 5 years is $ 11364 .

Step-by-step explanation:

The exponential decreases function is defined as

Where a is the initial value , r is the rate of interest in the decimal form and t is the time in years .

As given

Don bought his car for $20,350.

It is expected to depreciate an average of 11% each year during the first 5 years.

a = $ 20350

11% is written in the decimal form

= 0.11

r = 0.11

t = 5 years

Put all the values in the function

y = $ 11363 .5621

y = $ 11364 (Approx)

Therefore the approximate value of Don car be in 5 years is $ 11364 .

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
