Determine if the rates $168 rasied for washing 24 cars and $280 rasied for washing 40 cars are equivalent

We are given : $168 raised for washing 24 cars and $280 raised for washing 40 cars.

We know the rate formula.

Rate = Total amount ÷ Total numbers.

Let us find value of each rate for  the given problem.

Rate 1: Total amount ÷ Total numbers = $168 ÷ 24 = $7.

Rate 2: Total amount ÷ Total numbers = $280 ÷ 40 = $7.

We can clearly see that Rate 1 is equal to Rate 2, that is $7.

So, we can say rates are equivalent.

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200

answer: 5

step-by-step explanation:

since, the range is the difference between the lowest and highest values of the given sample space.

and, here the sample space = { 3, 1, 0, 4, 1, 4, 2, 3, 0, 5, 0, 1, 1, 2, 0, 4, 1,4, 4 ,2 ,3 ,2 ,0 ,1 ,4 }

here, the highest value of the given sample = 5

and, the lowest value = 0

therefore, the range of the sample space = 5 - 0 = 5
