Answer:
The correct answer is D. 3 % p. a .
Step-by-step explanation:
For the investment offered, Martin is supposed to get $180 as an interest ($6,180 - $6,000).
Now Martin is borrowing $6,000 from the bank to make this investment. He should be charged $180, so that he breaks even on investment.
Thus using the formula:
Interest= Principal × Time ( per annum) × 
; (Here simple and compound interest are same as the sum borrowed is to be charged for a single year)
⇒ 180 = 
× 1 × Interest rate
⇒ 180 = 60 × Interest rate
⇒ Interest rate = 3
Thus the correct answer is 3% per annum.
Answer:
15
Step-by-step explanation:
(18+22+17+x)/4=18
18+22+17+x=18×4
57+x=72
x=72-57
x=15
Answer:
i cant see it
Step-by-step explanation:
All real numbers.
Step-by-step explanation:
Distributive property: a(b+c)=ab+ac
Expand: 4(a+2)=4a+8
Expand again: 14-2(3-2a)=4a+8
4a+8=4a+8
You subtract by 8 from both sides of an equation.
4a+8-8=4a+8-8
Simplify.
4a=4a
Then, subtract by 4a from both sides of an equation.
4a-4a=4a-4a
Finally, simplify.
4a-4a=0
0=0
True
All real numbers is the final answer.
Hope this helps you!
Have a nice day! :)
