Answer:
(90)(7) ⇒ the error was multiplying 90 and 7.
Step-by-step explanation:
12(597) = 12(500 + 90 + 7)
= 12(500) + (90)(7)
= 6000 + 630
= 6,630
The part in bold shows where the error is. It was not correct to multiply 90 and 7.
The process was to proceed as follows:
12(597) = 12(500 + 90 + 7)
= 12(500) + 12(90) + 12(7)
= 6000 + 1080 + 84
= 7,164
3x + 5x = 320
8x = 320
x = 40
3(40) : 5(40) = 120 : 200
The best answer would be Option C.
Answer:
It will be $506.876 more.
Step-by-step explanation:
The equation for continuously compounded interest is given by
.......... (1)
where, A is the final amount, P is the principal amount, r is the annual interest rate and t is the number of years.
Now, in our case, P = $500, r = 7% i.e 0.07 and t = 10 years.
Then, from equation (1),
dollars
Therefore, the interest will be (A - P) = $(1006.876 - 500) = $506.876. (Answer)
