A boat that sold for $12,500 had a sales tax of $562.50. How much is the tax on a boat that sells for $9,550?
Degger [83]

Answer:

$429.75

Step-by-step explanation:

First, find the tax rate on the sale of the boat:  Let r represent that rate.  Then,

$12,500r = $562.50.  Solving for r, we get r = $562.50 / $12,500 = 0.045

The tax rate is 0.045, or 4.5%.

Applying this tax rate to a boat selling for $9,550:

0.045($9,550) = $429.75.  This is the amount of tax on the 2nd boat.

The distance y (in centimeters) a spring is compressed by a force x (in kilograms) is given by
kirza4 [7]

Answer:

(x, y) = {(20, 1.3), (40, 2.6), (60, 3.9), (80, 5.2), (100, 6.5)}

Graph C represents the table of values

Step-by-step explanation:

To complete the table, substitute each value of x into the equation, y = 0.065x, to find each corresponding y-value.

Thus:

✔️When x = 20:

y = 0.065x

y = 0.065(20)

y = 1.3

✔️When x = 40:

y = 0.065x

y = 0.065(40)

y = 2.6

✔️When x = 60:

y = 0.065x

y = 0.065(60)

y = 3.9

✔️When x = 80:

y = 0.065x

y = 0.065(80)

y = 5.2

✔️When x = 100:

y = 0.065x

y = 0.065(100)

y = 6.5

✔️<em>The graph of that represents this table of values is graph C. See attachment.</em>
