Answer:
3 7/12
Step-by-step explanation:
First find the common denominator.
8,16,24
3,6,9,12,15,18,24
Once you find the common denominator. You have to fix the numerator.
7 2/8 would become 7 6/24
Whole numbers stay the same.
8 x 3 = 24
2 x 3 = 6
Now we repeat it on the other mixed number.
3 2/3 would become 3 16/24
Again whole numbers stay the same.
3 x 8 = 24
2 x 8 = 16
Once you convert the fractions to having the same denominator you subtract like normal.
7 6/24 - 3 16/24 = 3 14/24
3 14/24 can be simplified to 3 7/12
900 x² + 500 x= 1600 /:100
9 x² + 5 x = 16
9 x² + 5 x - 16 = 0
x 1/2 =

x = 1.084
The interest rate:
r = x - 1 = 1.084 - 1 =
0.084 = 8.4 %Answer: D) 8.4 %
