That is a representation of a number using variables, but we'll just say it's for place values.
A is in the Tens Place B is in the Ones Place C is in the Tenths Place (1/10) D is in the Hundredths Place (1/100
Since we are talking about money let's put it in relation to a dollar.
A is in the Ten Dollar Place B is in the One Dollar Place C is in the Tenth of a Dollar Place (1/10 of a dollar) D is in the Hundredth of a Dollar Place (1/100 of a dollar)
So, what is 1/10 of a dollar? What amount of money times 10, would get you 1 dollar. Or you can think of it as if you had 10 of one value of money and you got a dollar what is that? A dime.
Now, what is 1/100 of a dollar? What amount of money times 100, would get you 1 dollar. 1 cent (Or it is sometimes called a penny).
So that means any number beyond the 1/100 of a dollar point (D) will be rounded. If it's the first number after the 1/100 of a dollar is greater than (or equal to) 5 then we round the cent value up. If it is less than 5 we round down.
$29.4983 So, 9 is our cent place. 8 is greater than 5, so we round 9 up. (Add 1. Since it is 9 it will carry over into the 1/10 of a dollar place) Our answer is: $29.50
The first thing we must do for this case is to observe the highest relative frequency of the table in the total column. For the white car we have: Male = 0.11 Female = 0.20 Total = 0.31 The percentage is given by: (0.31) * (100) = 31% Answer: The percentage that represents the car bought most often is: 31%
