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= (x)/(100)*7,000`


`(x)/(100)= (77)/(7000)= (11)/(1000)= (1.1)/(100)`

so the fee is 1.1% of the cost.

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


`(1.1)/(100)*9,200=1.1*92= 101.2` $
