Rachel bought 3 CDs that were each the same price. Including sales tax, she paid a total of $35.40. Of that total, $2.70 was tax. What was the price of each CD before tax?

Step-by-step explanation:

Total bill - the tax = cost of 3CD's

Our total bill is $35.40, the tax is $2.70, therefore,

35.40 - 2.70 = cost of 3 CD's so

3 CD's = $32.70

Divide that by 3 to get the cost per CD:

32.7 / 3 = $ 10.90 per CD

  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.
