8.544 is the sqare root with a remainder
Answer:
(a) Equation:
(b) 7.5 gallons
Step-by-step explanation:
Given
Current Gas = 10 gallon
Every Hour = -1.25 gallon
Solving for (a): An equation for the scenario
This question represents an Arithmetic Progression and will be solved using the following formula:
Where
Substitute these values in the formula
Collect Like Terms
Solving for (b): In this case, n - 3
Substitute 3 for n in
<em>7.5 gallon of gas left</em>
Since both the expressions in x are equal to y then they are equal to each other, so
-2x + 3 = 13x - 4
-15x + 3 = -4
-15x = -7
x = 7/15
and y = -2(7/15) + 3 = 31/15 = 2 1/15
Answer: 19.4
Step-by-step explanation:
Given
Profit is given in terms of the selling price
to get the maximum price, differentiate y w.r.t x
Put to get maximum value
Thus, the company must sell it at 19.4
