Anita paid a total of $57. 50 for a blazer. The price of the blazer was $52. 85. What was the sales tax rate? A. 4. 56% B. 8. 08% C. 8. 79%.

r = 8.80%

Step-by-step explanation:

To find the tax rate, first determine how much the tax was

57.50 - 52.85 = 4.65

Then take the original price times the tax rate = tax

52.85 * r = 4.65

Divide each side by 52.85

r = 4.65/52.85

r =.087984863

Change to decimal form

r = 8.7984863

Rounding to the nearest hundredth

r = 8.80%

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
