Now say you invest the $6,500 and the highest interest rate you can find is 2.5% compounded annually, but you would have to leave the investment in the account for a minimum of 5 years. If you decide to wait 5 years to buy the car, how much more money will you have to save to buy a car at the $8,000 price?

$648.5

Step-by-step explanation:

Given data

Principal= $6,500

Rate= 2.5%

Time= 5 years

The compound interest formula is given as

A= P(1+r)^t

substitute

A= 6500(1+0.025)^5

A= 6500(1.025)^5

A=6500*1.131

A=$7351.5

After 5 years the money in the account will be $7351.5

Now to buy a car of  $8,000

The added amount will be  

=$8,000-$7351.5

=$648.5

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)

step-by-step explanation:

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
