Answer:
A) What was the absolute change from 1970 to 1990?
in 1970 we had $87.32
in 1990 we had $283.16
The absolute change is the direct difference:
$283.16 - $87.32 = $195.84
B) What was the relative change from 1970 to 1990?
Now we need to compare this with the initial value:
Relative change = 100%*(final value - initial value)/initial value.
Relative change = 100%*$195.84/$87.32 = 223.93%
C) What was the absolute change from 1995 to 2000?
in 1995 the price was $351.94
in 2000 the price was $349.69
The absolute change is:
$349.69 - $351.94 = -$2.25
The negative sign means the obvious thing, the price decreased.
D) What was the relative change from 1995 to 2000?
Relative change = 100%*(-$2.25)/($351.94) = -0.64%

Answer:
The other complementary angle measures 40 degrees.
Step-by-step explanation:
Given that one of the angles of a pairs of complementary angles is 50 degrees, to find the ratio of the pair of complementary angles, the following calculation must be performed, knowing that the sum of two complementary angles is equal to 90 degrees:
X + 50 = 90
X = 90 - 50
X = 40
Therefore, the other complementary angle measures 40 degrees.
20*65 = 1300
That's the price without tax.
Now to find tax:
1300*.035 = 45.5
1300+45.5 = $1345.5
$1345.5 is your total
