You just won a lottery prize.

d.
$340,000 to less than $360,000
e.
none of the above
ANSWER:
150,000/(1.07)^2 + 250,000 /(1.07)^3 = 131,015.81 + 204,074.47 = 335,090.28
2.
If Mary's taxable income is $20,000, then her taxes will be $4,000.
If her taxable income is $40,000,
then her income taxes will be $6,000.
This is an example of
a.
A progressive tax
b.
A proportional tax
*c.
A regressive tax
d.
None of the above
ANSWER:
When income is $20,000, Mary pays 20% in taxes (4,000/20,000 = .20).
When income is
$40,000, Mary pays 15% in taxes (6,000/40,000 = .15).
Thus, the tax is regressive.

ANSWER: If we move from C to B, we gain 2500 cell phones but we lose 8,000 suits.
The OC of a cell
phone is 8,000/2,500 = 3.20 suits per cell phone.
If we move from B to A, we gain 2500 cell phones
but we lose 8,000 suits.
The OC of a cell phone is 8,000/2,500 = 3.20 suits per cell phone.
If we move
from C to A, we gain 5000 cell phones but we lose 16,000 suits.
The OC of a cell phone is
16,000/5,000 = 3.20 suits per cell phone.
ANSWER: OC(cell phone) = 16,000/5000 = 3.2 suits
