Answer:
$519.6048
Step-by-step explanation:
Cost of subscription is $499 + 8% tax for 30 days
Cost of subscription for 30 days = $499
Cost of subscription for 1 days = ![\frac{499}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B499%7D%7B30%7D)
So, Cost for (30-7 = 23)days = ![\frac{499}{30} \times 23](https://tex.z-dn.net/?f=%5Cfrac%7B499%7D%7B30%7D%20%5Ctimes%2023%20)
= ![382.56](https://tex.z-dn.net/?f=382.56)
Cost of subscription for 23 days = ![382.56](https://tex.z-dn.net/?f=382.56)
Sale tax = 8 %
Sales Tax = ![30.6048](https://tex.z-dn.net/?f=30.6048)
Cost of subscription = $499+$30.6048 = $529.6048
There is an off of $10
So, Final cost = $529.6048-$10= $519.6048
Hence The final cost is $519.6048
