Answer:

7 females, 24 males

Step-by-step explanation:

I solved it by using this equation:

2x + 17 = 31

then, i subtracted 17 on both sides:

2x=14

then divide by 2 on both sides:

x=7

then I added 7 to 17 to find the number of males:

7+17= 24

Paul lands a home mortgage of $58,200 at a
qwelly [4]

Answer:

$72,100

Step-by-step explanation:

To calculate the total principal+interest payment, you can use the formula to find the future value:

FV=PV(1+i)^n

FV= Future value

PV= Present value= $58,200

i= Interest rate= 7.40%

n= Number of periods of time= 3 years

Now, you can replace the values on the formula:

FV=58,200*(1+0.0740)^3

FV=58,200*(1.0740)^3

FV=72,100

According to this, the answer is that the  total principal + interest  payment will be $72,100.
