Question

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.

Answer 1

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.

`(x)/(9900) =(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.

`(9900x)/(9900) =(9900*82)/(9200)`

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

`x=88.24`

Conclusion:

$88.24 is the licence fee for a car that cost $9,900.
