If a subscription is $499 plus 8% tax for 30 days, but is being prorated for 7 days, plus there is a $10 off coupon, what's the final cost?

The final cost is $115.74.

Step-by-step explanation:

Total amount of 30 days with tax = = 538.92 dollars

This value is for 30 days, and its prorated for 7 days, so value for 7 days is =

= 125.74 dollars

And $10 is off, so final cost is dollars

(Suppose the discount coupon is applied at the end of billing)

The final cost is $115.74.

answer: $34.31

step-by-step explanation:

$11.99 x 3 = $35.97

$35.97 - 10% = $32.37

$32.37 + 6% = $34.31

  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.
