Aron wrote the function f(x)=25x-15 find the amount of money he would make after washing x cars. select all that are in the domain of aron’s function. a-2 b-2.3 c-5 d-7.1 e-10

A. 2

C. 5

E. 10

Step-by-step explanation:

If x represents the number of cars that wash Aron then the domain of x must contain only the whole and positive numbers (natural numbers)

This, because Aron can not wash -4 cars, it would be absurd then that x was a negative number.

In the same way Aron can not wash 1.57 cars. Or washed 1 car or washed 2, it is not consistent in this case to say that washed a car and a half, for example.

Therefore the correct answer is the options

A. 2

C. 5

E. 10

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
