Answer:
-The amount he earns on a car that sold for $55,000 is $1,925.
-He has to sell 3.12 card to earn $6,000 comission.
Explanation:
To find the amount that he earns on a car that sold for $55,000, you have to calculate 3.5% of that amount:
$55,000*3.5%=$1,925
The amount he earns is $1,925.
Also, to find out the amount of cars he has to sell at this price to earn $6,000 commission, you have to consider that the amount Ed earns is equal to the total sales for the 3.5%, which is:
Comission=total sales*3.5%
The total sales would be equal to 55,000 for the number of cars and you can replace the comission with 6,000 and solve for the number of cars:
6,000=(55,000*number of cars)*0.035
6,000/0.035=55,000*number of cars
171,428/55,000=number of cars
number of cars=3.12
According to this, the answer is that Ed has to sell 3.12 card to earn $6,000 commission.
