$20.50 x .3 = 6.15
20.50 - 6.15 = $14.35
The book is now $14.35
Because the account PAYS compound interest per year it's called depreciation.
So you do 100-3.4 = 96.6, the divide by 100 = 0.966
Then you do 0.966^3 x £6000 = £5408.6
4,6,8 are being counted by twos so the next one is 10
4•3= 12, 6+3=9, 8-3=6, the next operation I assume would be division so 10/3= 3.34
To find the constant variation, solve for only one hour (in this case).
Divide 100 with 2
100/2 = 50/1
Each hour is 50 miles driven, so your constant variation is 50 mph
Okay. So, one temperature is positive and the other one is negative. Let’s find the absolute value (distance from 0) for both numbers. -21 is 21 units away from 0 and 6 is 6 units away from 0. 21 + 6 = 27. The difference of temperature from 8 AM to 9 AM is 27 degrees.
