B. Barbara's equation did not consider the number of bottles of iced tea. She only put 1.49, which would mean she only sold one. Because we know she sells more then one, it should be 1.49(then a variable)

Let D = the amount of money Deanna has after x games.
We know Deanna started with $15 and she spends 0.75 per game, so we can make the following equation:
D = 15 - 0.75x
Let L = the amount of money Lisa has after x games.
We know Lisa started with $13 and she spends 0.50 per game, so we can make the following equation:
L = 13 - 0.5x
The question is asking how many games need to be played for L and D to be equal, so just equate L and D and solve for x:
D = L
15 - 0.75x = 13 - 0.5x
15 - 13 = -0.5x + 0.75x
2 = 0.25x
2 = (1/4)x
8 = x
Therefore they need to play 8 games each to have the same amount of money.
Answer:
(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
