Answer:
Whitney can bring <u>6 friends.</u>
Step-by-step explanation:
The reason why is this:
Whitney is bringing 400 pounds of things plus <u>her own body weight! </u>
400 + 165 = 565 pounds
Now we add on Whitneys freinds which is <u>165 (their body weight) + the 10 pounds of gear which equals 175 pounds. So each friend would be 175 pounds total weight. </u>
175 x 6 = 1,050 pounds
If we add on Whitneys total weight thats:
565 + 1,050 = 1,615
<u>Adding on another friend would be 1,790 pounds which would be over the weight limit for the vehicle. </u>
Hence, Whitney can bring along 6 friends for her birthday.

Answer:
N = 920(1+0.03)^4t
Step-by-step explanation:
According to the given statement a car repair center services 920 cars in 2012. The number of cars serviced increases quarterly at a rate of 12% per year after 2012.
Rate is 12 % annually
rate in quarterly = 12/4= 3%
We will apply the compound interest equation:
N=P( 1+r/n)^nt
N= ending number of cars serviced.
P= the number of cars serviced in 2012,
r = interest rate
n = the number of compoundings per year
t= total number of years.
Number of compoundings for t years = n*t = 4t
Initial number of cars serviced=920
The quarterly rate of growth = n=4
r = 3%
The growth rate = 1.03
Compound period multiplied by number of years = 920(1.03)^4t
Thus N = 920(1+0.03)^4t
N = number of cars serviced after t years...
