Question

IF A 30-DAY SUBSCRIPTION IS $499 PLUS 8% TAX, BUT IS BEING PRORATED FOR 7 DAYS, PLUS THERE IS A $10 OFF COUPON, WHAT'S THE FINAL COST?

Answer 1

Answer:

$519.61

Step-by-step explanation:

We add the 8% tax 23 days of subscription since prorated for 7 days [30 - 7 = 23].

How much is 23 days subscription if 30 days is 499?

$\frac{30}{499}=\frac{23}{x}\\30x=23*499\\30x=11,477\\x=382.57$

We add 8% of this to 499:

0.08 * 382.57 =30.51

So cost is:

499 + 30.61 = 529.61

Now we have $10 off, so final cost would be:

529.61 - 10 = $519.61
