A certain college graduate borrows $8000 to buy a car. The lender charges interest at an annual rate of 10%. Assuming that inter

MaRussiya [10]

Answer:

The payment is $k=\$3216.92$ .

Interest paid during the 3-year period is $I_{T}=\$1651.76$

Step-by-step explanation:

The Payment amount

We are going to use the formula below with $VP=\$8000, i=10\%$ and $n=3$ .

$k=\frac{VP}{[\frac{1-(1+i)^{-n}}{i}] } =\frac{8000}{[\frac{1-(1+0.1)^{-3}}{0.1}] }=3216.92$

Interest paid during the 3 year

First period

$I_{1}=VP*i=8000*0.1=800$

$CS_{1}=k-I_{1}=3216.92-800=2416.92$

$Balance_{1}=VP-CS_{1}=8000-2416.92=5583.08$

Second period

$I_{2}=B_{1}*i=5583.08*0.1=558.31$

$CS_{2}=k-I_{2}=3216.92-558.31=2648.61$

$Balance_{2}=VP-CS_{2}=5583.08-2648.61=2924.47$

Third period

$I_{3}=B_{2}*i=2924.47*0.1=292.45$

Sum of Interest paid during the 3 years

$I_{t}=I_{1}+I_{2}+I_{3}=800+558.31+292.45=1651.76$

What is -3 > s + 5 ?

loris [4]

To solve for s you'll have to subtract 5 on both sides.

-3 > s + 5
-3 - 5 > s
-8 > s

Hope this helps :)

Darya [45]

Answer:

$129

Step-by-step explanation:

Let us represent:

Cost Adult tickets = x

Cost Children's tickets = y

The total cost of ticket = C =

A family goes to an amusement park adult tickets cost $21 children under 10 years of age pay $15

C = $21 × x + $15 × y

C = 21x + 15y

The total cost of 4 adult tickets and 3 children's tickets is calculated as:

C = 21 × 4 + 15 × 3

C = 84 + 45

C = $129
