An amount of $40,000 is borrowed for 11 years at 7 5% interest compounded annually. If the loan is paid in full at the end of th

valina [46]

Amount to be paid back = $ 88,624.36

Step-by-step explanation:

Principal amount = $ 40,000

Rate of interest = 7.5%

Number of years = 11

$A=P\left(1+\frac{r}{n}\right)^{n t}$

Plugin the values as,

$A=40000\left(1+\frac{7.5}{100}\right)^{11}$

$A=40000(1+0.075)^{11}$

$A=40000(1.075)^{11}$

$A=\$ 88,624.36$

Solve each equation. 1. 25 - 3x = 40 2. } (x – 10) = -4

nordsb [41]

Step-by-step explanation:

For no 1

25 - 3x = 40 

- 3x = 40 - 25 

- 3x = 15 

 - x = 15 / 3

Therefore x = - 5 

Now for no. 2

1/3 ( x - 10) = - 4 

( x - 10 ) = - 12 

x = - 12 + 10

Therefore x = - 2 

Hope it will help :)
