Answer:

a=b+k−u

Step-by-step explanation:

u=b+k−a

−a+b+k=u

−a+b+k+−b=u+−b

−a+k=−b+u

−a+k+−k=−b+u+−k

−a=−b−k+u

−a−1=−b−k+u−1

a=b+k−u

The licene fee for a car which costs $9,200 is $82. at the same rate, what is the licence fee for a car that cost $9,900.

vichka [17]

Step 1: Assign variable for the unknown that we need to find.

Let 'x' be the licence fee for a car that cost $9,900.

Step 2: Set up a proportion based on the given information.

$\frac{x}{9900} =\frac{82}{9200}$

Step 3: Solve for x

To get x alone we need to undo whatever is done to x. So multiply 9900 on both sides of the equation.

$\frac{9900x}{9900} =\frac{9900*82}{9200}$

Simplifying fraction on both sides of the equation, we get...

$x=88.24$

Conclusion:

<u>$88.24 is the licence fee for a car that cost $9,900.</u>

Bob owns a watch repair shop. have the lowest cost? operating his shop s given by C·2x2 He has found that the cost o 216x + 1 1

goldfiish [28.3K]

Answer:

The number of watches must he repair to have the lowest cost is 54.

Step-by-step explanation:

The cost of operating Bob's shop is given by

$C(x)=2x^2-216x+11243$

Differentiate the given function with respect to x.

$C'(x)=2(2x)-216(1)+(0)$

$C'(x)=4x-216$ ... (1)

Equate C'(x) equal to 0, to find the critical point.

$0=4x-216$

$216=4x$

Divide both sides by 4.

$\frac{216}{4}=x$

$54=x$

Differentiate C'(x) with respect to x.

$C''(x)=4$

C''(x)>0, it means the cost of operating is minimum at x=54.

Therefore the number of watches must he repair to have the lowest cost is 54.
