Yes, if the rational number can be simplified like 2/10 (20) then yes it can be whole number.
I= Ishaan's age= 2C
C= Christopher's age
35 years ago means we have to subtract 35 from their current age. Ishaan minus 35 equals 7 times Christopher minus 35 years.
CHRISTOPHER'S AGE:
I - 35= 7(C-35)
substitute I=2C in for I
multiply 7 by all in parenthesis
2C - 35= 7C - 245
add 35 to both sides
2C= 7C - 210
subtract 7C from both sides
-5C = -210
divide both sides by -5
C= 42 Christopher's age
ISHAAN'S AGE:
I= 2C
substitute C=42 to find Ishaan's age
I= 2(42)
I= 84 Ishaan's age
CHECK:
Substitute answers in original equation
I - 35= 7(C-35)
84 - 35= 7(42-35)
49= (7*42)+(7*-35)
49= 294-245
49=49
Hope this helps! :)
Answer:
48.67
Step-by-step explanation:
31 divided by 2 = 15.5 which is the radius
15.5 times by 3.14(pi) = 48.67
Let the amount be x.
6% for the first 160000
= 6/100 * 160000 = 9600
4% for any amount exceeding 160000.
= 4/100 * (x -160000) = 0.04(x-160000)
The sum of both commission should be equal to 10560.
9600 + 0.04(x -160000) = 10560
0.04(x -160000) = 10560 - 9600
0.04(x -160000) = 960 Divide by 0.04.
(x -160000) = 960/0.04
(x -160000) = 24000
x = 24000 + 160000 = 184000.
Selling price = 184000
