Answer:
M= -1
Step-by-step explanation:
B<4,000 is the inequality because b is less than 4,000
We would be able to answer if you provided or uploaded the table mentioned in the question. Without the prices, we can't do anything.
Answer:
Slope of the graph
gallons per dollar.
Intercept is 3000.
Step-by-step explanation:
General format of an equation of a linear graph is;
y=mx+c
Where,
y is the dependent variable
m is the slope of the graph
x is the independent variable of the graph
c is the intercept of the graph.
m(0)=3000 means when we substitute 0 for x values of the graph the y value is 3000. Therefore the intercept is 3000.
Slope of the graph = 
=
gallons per dollar.
So we can write the equation as;

but in this question y is given as m. Therefore function can be re-written as:

The graph is attached with the answer.
Let the original price of the sweater be = X
Then the amount Jerome pays for the sweater after 20% discount = X - (20X/100)
= X - 0.2X
= 0.8X
Now on this price the 8.25% tax needs to be added to get to the amount actually paid by Jerome.
So,
0.8X + [(8.25/100) * (0.8X) = 25.1
This is the equation from which the actual price of the sweater bought by Jerome can be determined.
So
0.8X + [(.0825) * ( 0.8X) = 25.1
0.8X + 0.066X = 25.1
0.866X = 25.1
X = 25.1/0.866
= 28.98
So the actual price of the sweater is $28.98.
