Tim has been saving for a down payment on a car. He invested $4,000 in an account earning 2.5% interest compounded semi-annually. After 7 years, he is ready to buy his new car. How much does he have in his account for a down payment? Round your answer to the nearest cent. Do NOT round until you have calculated the final answer.

Step-by-step explanation:

The expression for compound interest is given as

A=P(1+r)^t

given data

P=$4,000

r=2.5%= 0.025

t=7years

The final amount can be solved as

A=4000(1+0.025)^7

A=4000(1.025)^7

A=4000*1.1886

A=4754.4

The amount on the account is $4754.4

step-by-step explanation:

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
