Answer:
.09
Step-by-step explanation:
It is this because if you divide 9 by 100 it will equal .09.
The way you can solve percents is you do this (100+60-35). but you can change the numbers I'm just giving an example
Answer:
16 ribbons
Step-by-step explanation:
Given the length of the chain as 10
and there is a ribbon tied to it every , we can take the total length of the chain and divide by the measure of :
When dividing with fractions, we use the rule of 'keep/change/flip' to keep the first fractions, change the operation to multiplication and flip the second fraction.
C = 0.5x + 10
----------------------------------------------------------
Switch side :
----------------------------------------------------------
0.5x + 10 = c
----------------------------------------------------------
Take away 10 from both sides :
----------------------------------------------------------
0.5x = c - 10
----------------------------------------------------------
Multiply by 2 through :
----------------------------------------------------------
x = 2c - 20
----------------------------------------------------------
Answer : x = 2c - 20 (Answer A)

Answer:
1) $4400
2) $4400
Step-by-step explanation:
Let
X = price in first year
Y = price in 2nd year
Z = price in 3rd year
A = price in the end of 3rd year
Y = 1.1 X
Z = 0.8 Y
substitute Y into Z get Z = 0.88 X
A = 1.25 Z= 1.25(0.88X) = 1.1 X
1)
(125/100) Z = 22000
Z = 22000 x 100 / 125 = 17600
Z = 0.8Y
Y = Z/0.8 = 1.25Z
Amount of dollar decrease in 2nd year = Y - Z
= 1.25Z - Z = 0.25Z = 0.25 x 17600 = 4400 dollar
2)
Decrease in price over first 2 years = Increase in property in 3rd year - 2000
Hence, X - Z = (A-Z) - 2000
X - 0.8X = 1.1 X - 0.88 X - 2000
X - 0.88X - 1.1X + 088X = -2000
-0.1 X = -2000
0.1 X = 2000
X = 20000
Amount of dollar decrease during 2nd year = Y - Z = 1.1X - 0.88X = 0.22X
= (0.22) x (20000) = 4400 dollars
