Answer:
The fixed amount Geet earns for each television is <u>$60</u>.
Step-by-step explanation:
Given:
Geet sells televisions. He earns a fixed amount for each television and an additional $ 30 if the buyer gets an extended warranty.
If Geet sells 17 televisions with extended warranties, he earns $ 1,530.
Now, to find the fixed amount Geet earns for each television.
Let the cost of fixed amount be .
Number of television = 17.
He earns total = $1,530.
He earns additional amount = $30.
Now, to get the fixed amount we put an equation:
<em>Subtracting both sides by 510 we get:</em>
<em>Dividing both sides by 17 we get:</em>
Therefore, the fixed amount Geet earns for each television is $60.
