mark earns $1,250 for selling a $25,000 car. which sale listed has the same commission rate?
a) $750 commission on a $15,000 car sale
b) $3,000 commission on a $30,000 car sale
c) $1,000 commission on a $40,000 car sale
d) $2,560 commission on a $32,000 car sale
i already know the answer is not d.

The answer is A.

Step-by-step explanation:

If Mark earns 1250 for selling a 25000 car, that means he earns 5% commision because 1250 divided by 25000 is 0.05. And 0.05 equals 5%. Then you just try each of the answers. Since 15000 times 0.05 does equal 750, that means answer A has the same proportion as the example in the question.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

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.
