Answer:
$ 358,063
Explanation:
Calculation for the amount that Ruby's IRA will be worth when she needs to start withdrawing money from it when she retires.
Ruby's IRA worth when she retires at age of 65
First step
Using this formula to find how many years until Ruby retires
Time period= Retired age (-) current age
Let plug in the formula
65-25=40 years
Second step is to find the future value of IRA when she retires
Using this formula
Future value of IRA when she retires
= Present value(1+r)t
Let plug in the formula
$ 11,400 (1+0.09) ^40
=$11,400 (1.09) ^40
=$ 11,400 (31.409)
= $ 358,063
Therefore the amout that Ruby's IRA will be worth when she needs to start withdrawing money from it when she retires will be $358,063
The correct answer is any amount higher than $5,400.
First, you need to solve the break even point of sales when Chris will earn the exact same amount by plan a or plan b. The following equation will solve this problem, with x being the amount of sales.
$360 + .09x = $630 + .04x
First, subtract .04x from both sides:
$360 +.05x = $630
Next, subtract $360 from both sides:
.05x = $270
Finally, divide both sides by .05:
X = $5,400
At $5,400 Chris will earn the same about of pay, regardless of which plan they are on. Since the commission percentage is higher on plan a, Chris is better off having plan a when sales are higher than $5,400. At this point Chris is earning 9% commission, rather than 4% in plan b.
Solution:
Sum Present value of 60 payments
Rent 2000
Periods 60
Rate 12%
Present value of 60 payments $94,405 (Excel = PV( 1% , 60 , 2000))
Future value of these payments at t=9
Future value $1,03,249.99(Excel=FV(1%,9,94,405)
Periods 51
Rate 12%
Answer:
250 hours.
Explanation:
Cost of course : $500
The extra income from the course is $2 per hour
to pay off the cost of the course requires earning $500 by working at a rate $2 per hour.
Number of hours required = $500/2
=250 hours.
