Answer:
V= $8
Step-by-step explanation:
Letting V denote the value of an hour,
the annual value of the time savings from the change can be written as
= (5 days/week × 50 weeks/year × .25 hours/day) × V, or 62.5 V per year.
The present value of 62.5 V per year, forever, at a 5% discount rate, is
= 62.5 V / 0.05.
The implication of the change in house prices is that households were willing to pay $10,000 to gain 15 minutes per commuting day, i.e., that the present value of the time savings is $10,000.
Setting 62.5 V / 0.05 = $10,000 and solving gives V = $8

Step-by-step explanation:
Looking at the question, I'm assuming it has a mistake.
However, I will first attempt to solve it normally:
Simply combine like terms to get 5x = 180, and thus x = 36, and y = 72
The first mistake possibility is that the first equation should be <u>3x + 2y = 180</u>
If that is the case, simply substitute in 2x for y, turning the equation into
3x + 2 (2x) = 180
3x + 4x = 180
7x = 180
Thus, x = 25.715 and y = 51.43
Another possible mistake is that the first equation should be <u>3y + 2x</u><u> </u><u>= 180</u>
Solve similar to the first mistake
3 (2x) + 2x = 180
6x + 2x = 180
8x = 180
Thus, x = 22.5, and y = 45
