Answer and explanation:
Profit from sale of model boats = Sales -costs(costs of goods purchases + expenses or charges by the local fair)
John's profit from the sale of model boats can be represented by the equation:
P= 50x-(5x+80)
Where P is profit from the sale of the model boats and x is number of model boats bought and sold. The 80 is constant as it is a fixed cost paid to the local fair.
For example if John buys and sells 20 model boats, he would make profit of:
Substitute x=20 in equation above
P= 50×20-(5×20+80)
P=1000-180
P=$820
It could be said that John is in a very profitable business and his profit is also dependent on volume of sales because the lower his sales the closer he gets to making a loss and not profit

Answer:
4 months.
Step-by-step explanation:
We can write formulas for the amount each person paid after x months. These will be
Brian = 60 + 42.95x
Michael = 0 + 57.95x
So for example, after 1 month Brian will have paid 102.95 for the installation and first month, while Michael will have paid only 57.95 (I put the zero in the equation to make it look like the familiar y-intercept form). We are trying the find the month at which they have paid equal amounts. Solve for x in the equation
60 + 42.95x = 57.95x
60 = (57.95 - 42.95)x
60 = 15x
x = 4
After four months.
Answer:
No because (6, 4) is on the line
Step-by-step explanation:
x = 6
y = 4
1
4 > 
------- 6 + 7
2
6
4> ------ + 7
2
4 > -3 + 7
4 > 4
that is not true so the answer is no because ( 6, 4) is on the line
