A) Interest = principal * rate * time
I = (800)(0.05)(3) = $120
b) $800 + $120 = $920 after the three years. $920 * (1 - 0.02) = $901.60.

Answer:
The average service rate ($73) is far greater than the least service rate ($11), and far less than the highest service rate ($103).
Step-by-step explanation:
The service rate was given as $11, $84, $94 and $103.
The average service rate =
=
=
= 73
Their average service rate is $73.
But comparing the average service rate to their given service rates, the average service rate ($73) is far greater than the least service rate ($11), and far less than the highest service rate ($103).
If we assume that Jane spent $ x on the black pack
Then the cost of the book is $ 20 less that twice the cos of the black pack,
Then twice the cost of black pack is 2x, then less $ 20 we get 2x-20
Hence , 60 =2x-20
solving for x
x = 40
Therefore, the cost of the black pack is $40.
