Question

A tennis star was hired to sign autographs at a convention. She was paid 3000 plus 2% of all admission fees collected at the door. The total amount she received for the day was 3540. Find the total amount collected at the door

Answer 1

Let x be the total amount collected at the door. Then, we can write

`3000+(0.02* x)=3540`

where the 0.02 denotes the comission of 2%. From this equation, we can find x.

Then, by moving 3000 to the right hand side, we have

`\begin{gathered} 0.02x=3540-3000 \\ \end{gathered}`

which gives

`0.02x=540`

Now, by moving 0.02 to the right hand side, we get

`x=(540)/(0.02)`

then, x is given by

`x=27000`

Therefore, the total amount collected at the door is $ 27 000.
