Question

The license fee for a car which cost $9,200 is $82. At the same rate, what is the license fee for a car that costs $9,900? Round your answer to the nearest cent.

Answer 1

Because we know that both cars have the same rate for tax, we can set their ratios equal to each other:
`(82)/(9200) = (x)/(9900)`

Cross-multiply:
`82 * 9900 = 9200x`

Simplify:
`811800 = 9200x`

Divide both sides by 9200:
`x = 88.2391304347826`

They told us to round the solution to the nearest cent. Which gives us
`x=$88.23`
