Answer:

Step-by-step explanation:

Use the exponential function

v(t)=a(b)^t where a is the initial value of the car, b is the rate of decay, and t is the time in years. For us, a = 18000, b = (1 - .15), so the model for this car is:

v(t)=18000(.85)^t  We can use this model now to find the value, v(t), of the car after 3 years has gone by (from 2006 to 2009 is 3 years):

v(t)=18000(.85)^3 and simplifying a bit:

v(t) = 18000(.614125) so

v(t) = 11054.25

Round however you need to.

Fran deposited 4869 into a savings account that pays simple annual interest rate of 3.25% how much interest will she earn after
Whitepunk [10]

Answer:

$395.61

Step-by-step explanation:

The formula for simple interest is:

i=Prt

Where

i is the interest amount

P is the principal amount

r is the rate of interest per time period

t is the time period

Here,

P = 4869

we want to find after 30 months, that converted to years is:

30/12 = 2.5 years

t = 2.5

The annual rate is 3.25% = 0.0325

Now, substituting, we find our answer:

i=Prt\\i=(4869)(0.0325)(2.5)\\i=395.61

The interest earned is <u>$395.61</u>

No you cannot because the clothes alone with sales tax are $148.50, and you would need 20 more dollars plus 5 dollars for a meal for yourself if you wanted one.

Burka [1]

Answer:

Multiply the ones. 9 times 83 is 747. Multiply the tens. 30 times 83 is 2,490. Add the products to get 3,237.

The rest of the question:

Which gives the correct order of steps needed to multiply the problem below?   "83x39 "

The steps to multiply  83x39

1) multiply the ones 9 times 83 = 9 times 3 + 9 times 80 = 27 + 720 = 747

2) multiply the tens 30 times 83 = 30 times 3 + 30 times 80 = 90 + 2400 = 2490

3) add 747 and 2490 = 747 + 2490 = 3,237

According to the previous steps, the answer is option 3

Multiply the ones. 9 times 83 is 747. Multiply the tens. 30 times 83 is 2,490. Add the products to get 3,237.
