Ed sells cars at the local dealership. He earns 3.5% commission on all sales. What amount does he earn on a car that sold for $55,00? How many cars does he have to sell at this price to earn $6,000 commission?

-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.

Step-by-step 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.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
