Belinda bought a car for 10% off the $21,957.68 sticker price. The sales tax was 6.5% of the sale price. She had to pay a $528.0

Answer:

$21,574.43

Step-by-step explanation:

To start off, we need to take 10% off of the starting price of $21,957.68. We can do that by multiplying that number by 0.10. The work is shown below...

(21,957.68) x (0.10) = 2,195.77

Now we can take the number 2,195.77 and subtract that from our starting price.

21,957.68 - 2,195.77 = 19,761.91 (this is our price after the 10% sale)

Next, we need to add on the sales tax. We simply multiply 19,761.91 by the decimal version of 6.5% which is 0.065.

(19,761.91) x (0.065) = 1,284.52

Now we add that number to 19,761.91

19,761.91 + 1,284.52 = 21,046.43

Since we have our current cost after sales tax, we now just need to add the $528 license fee...

21,046.43 + 528 = $21,574.43

What is the rate of change and initial value for the linear relation that includes the points shown in the table?

uysha [10]

X 1 2 3
y 10 8 6
So find the slope m: (6-10)/(3-1) = -4/2 = -2
Going backwards when x = 0, y will be 12 (you can see this)
So
<span>Initial value: 12, rate of change: −2
