Solution:
Assume:
A=0
B=1
C=2
D=3
Formula:
185X - (10X * 2)/60 * 21 * 22 = ?
Cost Savings:
Apartment A = $0.00
Apartment B = $23.00
Apartment C = $46.00
Apartment D = $69.00
According to the time value, Apartment D provides the most savings.
Renting, which is three times less than Apartment A, compensates for 30 minutes each way (or 1 hour per day at $22/hr for 21 days). The rate of net income $405 is $336.
