Multiply through the second term by 
:
Recall that 
for all x :
If 
, we can cancel a factor of it in the second fraction.
and this simplifies to
Given:
1970 price of dish washing detergent in a bottle : $0.50
CPI
1960 = 29.60
1970 = 38.80
1980 = 82.40
(82.40 - 38.80) / 38.80 = 1.124
1.124 x 100% = 112.4% rate of increase
$0.50 * 112.4% = $0.562 is the 1980 price of the dish washing detergent.

Step-by-step explanation:
Answer:
Q' = ( -10 , 6 )
Step-by-step explanation:
P' - P = ( 18-12, -6-(-4)) = ( 6 , -2)
That is, the PQ line segment has moved 6 units to the right and 2 units to the bottom.
Q' - Q = ( 6 , -2 ) → Q' = ( 6 , -2 ) + ( -16 , 8 ) = ( -10 , 6 )
Answer: The correct answer is A.
