(a) The net profit for walking 3 dogs is $40
(b) The net profit for walking 6 dogs is $100
Step-by-step explanation:
There are mistakes in your question; however, the correct given parameter is

Required
Interpret p(3) = 40 & p(6) = 100
Interpreting p(3) = 40
Comparing this to 
d = 3 & p(d) = 40
This implies that:
The net profit for walking 3 dogs is $40
Interpreting p(6) = 100
Comparing this to 
d = 6 & p(d) = 100
This implies that:
The net profit for walking 6 dogs is $100

Step-by-step explanation:
10,080,000 (because 720×14, the total number of days he swam in two weeks, is 10,080 and then you divide it by .001, the number of kilometers in one meter, which gives you 10,080,00.)
Answer:
I am assuming any number in between these two, so let's just say 6,550.
Step-by-step explanation:
If you count up from 6,534, you will eventually get to 6,550. If you continue to count up, you will eventually reach 6,565 which is bigger than 6,550.
