17 + 23 = 40
The temperature rose 40 degrees.
It would be 20
21.3
-1.8
------
19.5 rounded would be 20
Formula for amount for compound interest:
Amount, A = P(1 + r/100)^n
Where r is rate, P is principal, and n is the number of years.
P = 2000, r = 5, n = t years.
A = 2000( 1 + 5/100)^t
A = 200(1+0.05)^t
A = 2000(1.05)^t
A(t) = 2000(1.05)^t
Distance=speed x time
so it would be 28 x 6=168
