Answer:
a. Yes. The difference is common and equal to $1750
b. $1750
c. $20000 was initial investment
d. This is linear equation with start point of 20000 and slope of 1750:
e. After another 10 years (on the top of 5 given) the investment will be:
- y = 1750*15 + 20000 = $46250
f. After 20 years the value of investment will be:
- y = 1750*20 + 20000 = $55000
x 20
------ = -------
100 125
(The percentage x saved is equal to 20 out of 120) Cross multiply:
125x = 20(100)
125x = 2000
Divide both sides by 125
x = 16%
Answer:
It is B. Commutative Property of Addition. I selected d from the other answer and it was wrong, just trust me it b. Commutative.
Hope this helps you.
7) 4/18 + 5/18 = 9/18 = 1/2
8) 3/18 + 4/18 + 5/18 = 12/18 = 4/5
