G Robert Hitchcock is 40 years old today and he wishes to accumulate $500,000 by his 65th birthday so he can retire to his summer place on Lake Hopatcong. He wishes to accumulate this amount by making equal deposits on his 40th through his 64th birthdays. What annual deposit must Robert make if the fund will earn 8% interest compounded annually

The correct answer is $6934.48.

Explanation:

According to the scenario, the given data are as follows:

Time period ( 41 - 64 years) (n)= 24 years

Rate of interest (r) = 8%

Future value (FV) = $500,000

Annual deposit amount = P

So, we can calculate the annual deposit amount by using following formula:

FV = P × (1+r) × [{ (1+r)^n - 1} ÷ r]

By putting the value, we get

$500,000 = P × ( 1 + 0.08) [{ (1+0.08)^24 - 1} ÷ 0.08]

$500,000 = P × ( 1.08) [{ (1.08)^24 - 1} ÷ 0.08]

$500,000 = P × ( 1.08) [{ 6.34118073724 - 1} ÷ 0.08]

$500,000 = P (72.1035)

P = $500,000 ÷ 72.1035

P = 6934.48

the answer is "b.the increased supply will create a surplus. "

the essential thought behind price controls is straightforward - utilize the power of law to modify the equilibrium of a market. for instance, the legislature may choose that the steel business needs to survive, and in this way pass a law to set a value floor on steel. this implies all steel sold must offer at or over the floor value, which must be set over the equilibrium cost for it to have any impact. the switch could likewise happen - the administration can choose that steel is excessively costly and set a value roof underneath its equilibrium value, with the goal that all steel must be sold at or beneath that ceiling.
