Question

The licesnce fee for a car which cost $7,000 is $77. At the same rate what is the license fee for a car that cost $9,200?

Answer 1

Let 77$ be x percent of 7,000$.

so 
$77= \frac{x}{100}*7,000$

$\frac{x}{100}= \frac{77}{7000}= \frac{11}{1000}= \frac{1.1}{100}$

so the fee is 1.1% of the cost.

This means the fee for a car costing 9,200$ is 

$\frac{1.1}{100}*9,200=1.1*92= 101.2$ $
