Answer:

5 shirts

Step-by-step explanation:

First, subtract the shipping from her money. 45 - 2.50 = 42.50. Now divide this by the price of each shirt. 42.50 ÷ 8.50 = 5. The shipping fee only applies once because it is for the entire order.

2. A landlord wants to acquire an additional apartment building for $250,000. The new building

Answer:

monthly payment is about $1422 (rounded)

"taking this loan would be a smart decision because even after paying off the loan, he is still making a handsome profit (because his income per month is more than his loan payment)."

Step-by-step explanation:

The loan is an annuity so we use the formula for annuity to find the monthly payments he has to make.

$PV=C*\frac{1-(1+r)^{-n}}{r}$

Where

PV is present value of the loan (250,000)

C is the monthly payment (what we are trying to find)

n is the number of months (30 years * 12 = 360 months)

r is the rate of interest per month ( i = 5.5%/12 = 0.0046)

Putting these values, we solve for C:

$PV=C*\frac{1-(1+r)^{-n}}{r}\\250,000=C*\frac{1-(1+0.0046)^{-360}}{0.0046}\\250,000=C*\frac{1-1.0046^{-360}}{0.0046}\\250,000=C*175.7332\\C=1422$

So monthly payment is about $1422 (rounded)

Since, each of the 8 apartments are going to be rented out at 500, total monthly income would be 8 * 500 = $4000

taking this loan would be a smart decision because even after paying off the loan, he is still making a handsome profit (because his income per month is more than his loan payment).
