Taxes on the property buyer Tamara is purchasing are $8,200, due on December 31. If the closing is set for June 29th, using the
rosijanka [135]

The buyer will be paying taxes for 185 days, so will pay

... (185/365)·$8200 = $4156

Your most appropriate choice seems to be $4178, which corresponds to 186 days' taxes.

_____

There are 30 days in each month in the last half of the year, plus 1 additional day in each of July, August, October, and December. The 30th of June also belongs to the buyer (but the 29th, closing day, does not), so there are 180+5 = 185 days for which the buyer must pay taxes. The answer choices don't include that value.

At what rate would you need to invest $12000 and make $2880 after 8 years?
lora16 [44]

Answer:

3\%

Step-by-step explanation:

we know that

The simple interest formula is equal to

I=P(rt)

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=8\ years\\ P=\$12,000\\I=\$2,880\\r=?

substitute in the formula above

2,880=12,000(8r)

Solve for t

2,880=96,000(r)

r=2,880/96,000

r=0.03

Convert to percent form

0.03*100=3\%

Jerry goes to the bank and borrows $9,000 for farm equipment. The simple yearly interest is 9.5% and he pays off the loan over a
creativ13 [48]
To solve this problem you must appply the formula for simple interest, which is:
 
 I = RxPxN
 
 I: Simple Interest.
 R:Rate (9.5$/100=0.095/12).
 P: The principal (P=$9000).
 N:number of periods (N=24).
 
 When you substitute these values into the formula, you obtain:
 
 I=RxPxN
 I=(0.095/12)x9000x24
 I=$1710
 
 Therefore, the monthly payment is:
 
 $1710/24=$71.25
 
 What is Jerry's monthly payment?
 
 The answer is: Jerry's monthly payment is $71.25
