2x/3=8
2x=24
x=12
It takes Molly 12 minues to run one mile.
(3 x 10^6)(8 x 10^-4) = (3 x 8) x 10^(6 - 4) = 24 x 10^2 = 2.4 x 10^3
Answer 2.63
Explanation 5.84-3.21=2.63
Initial cost, P = 15000
Annual depreciation, i = 0.23
Value at end of year n:
V(n)=P(1-i)^n
A. At end of year 1 (n=1)
V(1)=15000(0.77)= 11550
B. At end of year 3 (n=3)
V(3)=15000(0.77^3) = 6848.00
