Question

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?

Answer 1

$528.12

Explanation:

499-10

489×1.08= 528.12

Answer 2

The final cost is $115.74.

Explanation:

Total amount of 30 days with tax =
`499+(0.08*499)` = 538.92 dollars

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

`(538.92)/(30)*7` = 125.74 dollars

And $10 is off, so final cost is
`125.74-10=115.74` dollars

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

The final cost is $115.74.
