Answer:
1/-4
Step-by-step explanation:
(2,-3),(-2,-2)
-2 + 3/ -2 - 2
1/-4
You just have to find the greatest common factor for both 28 and 24, which is 4. You can make 4 packets with 7 milk chocolates and 6 dark chocolates.
This is the future value quadrupled in t years at an annual interest rate of 6.5% compounded daily. We need to find t.
1*(1+0.065/365)^(365t)t=4
take log on both sides,
365t(log(1+0.065/365)=log(4)
=>
365t=log(4)/log(1+0.065/365)
t=(log(4)/log(1+0.065/365))/365
=(1.38629/.000178066)/365
=21.33 years
Check with the rule of 69, applicable to continuous compounding (an approximation to current problem) to double money, it take 69/interest rate in % years.
=69/6.5
=10.62 years
To double twice (quadruple), it takes twice 10.62
=21.24 years, not that far from 21.33 that we got earlier.
