Answer:
The taxi drivers average profit per trip is $9.50.
Step-by-step explanation:
The taxi driver provides services in Zone A and Zone B.
Let = destination is in Zone A and = destination is in Zone B.
<u>Given:</u>
The probabilities are:
The Expected profit are:
If the trip is entirely in Zone A the expected profit is, E (A - A) = $7.
If the trip is entirely in Zone B the expected profit is, E (B - B) = $8.
If the trip involves both the zones the expected profit is,
E (A - B) = E (B - A) = $12.
Determine the expected profit earned in Zone A as follows:
Determine the expected profit earned in Zone B as follows:
The total expected profit is:
Thus, the taxi drivers average profit per trip is $9.50.

Answer:
11.4 mixture:26 and 2/3
7.8 mixture: 53 and 1/3
Step-by-step explanation: Sorry if this is hard to underestand. This is my first answer. This is a RSM question that has been checked.
11.4+7.8=9
x+80-x=80
Multiply
11.4x+624-7.8x=720
3.6x=96
1.2=32
0.6x=16
6x=160
x=26 2/3
80-26 2/3= 53 1.3
Answer:
25 years
Step-by-step explanation:
Given data
Principal P= $2000
Interest rate r= 6%
FInal amount A=$5,000
The simple interest formula is given as
A=P(1+rt)
substitute and solve for t
5000=2000(1+0.06*t)
5000=2000+120t
5000-2000=120t
3000=120t
t= 3000/120
t= 25 years
Hence, for a simple interest investment, she will be 25 years
