cost of 1 gallon gas = $2.09
cost of 3.785 litres gas = $2.09 ( 1 gallon = 3.785 litres)
cost of 1 litre gas = 2.09/3.785
cost of 18 litres gas = 2.09/3.785 * 18 = $20.982
Answer:
Part a) The approximate years were 1998 and 2008
Part b) The graph in the attached figure
Step-by-step explanation:
Part a) we have

For
Solve the quadratic equation


we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have

so
substitute in the formula
therefore
The approximate years are
1997+11=2008
1997+1=1998
Part b)
Using a graphing tool
we have


The solution of the system of equations is the intersection point both graphs
The intersection point are (0.99,80) and (11.23,80)
see the attached figure
therefore
The solution part a) is correct
Answer:
200 units
Step-by-step explanation:
The total income must be at least equal to the costs, and that is:
10*U = 5*U + 1000 Solving for U, which is the amount of units sold per month:
U = 1000/5 = 200 units.
Answer: The expression is 7/2.
