From 1980 to 1990, the consumer price index (cpi) increased from 82.4 to 130.7. if a gallon of apple juice cost $0.95 in 1980 and the price of apple juice increased at the same rate as the cpi from 1980 to 1990, approximately how much did a gallon of apple juice cost in 1990? a. $0.56 b. $0.82 c. $1.51 d. $1.31

The cost of the gallon of the apple juice is approximately $1.51 in 1990. (Option C)

Step-by-step explanation:

As it can be assumed that the increase of the gallon of apple juice is proportional to the increase of the CPI, we can state that the rate of the price of 1990 to the price of 1980 is the same than the rate of the CPI in 1990 to the CPI in 1980:

$130.7 / $82.4 = Pg (1990)/ $0.95

Where Pg (1990) is the apple juice gallon cost for 1990. By solving the equation above:

$130.7 / $82.4 * $0.95 = Pg (1990)

Pg (1990) = $1.5068 ---> Pg (1990) = $1.51

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
