Answer:
The final cost is $115.74.
Step-by-step explanation:
Total amount of 30 days with tax = [tex]499+(0.08\times499)[/tex] = 538.92 dollars
This value is for 30 days, and its prorated for 7 days, so value for 7 days is =
[tex]\frac{538.92}{30}\times7[/tex] = 125.74 dollars
And $10 is off, so final cost is [tex]125.74-10=115.74[/tex] dollars
(Suppose the discount coupon is applied at the end of billing)
The final cost is $115.74.
