A newspaper subscription costs $10/month. If you purchase an annual subscription you obtain a 20% discount on your total bill. How much do you end up paying if you go with the annual subscription?
Let's be accurate as possible and think first.
96
A year has 12 months.

If 1 month costs $10, then a year will cost $12 * 10 = $120 per year without an annual subscription.

If the annual subscription has a 20% discount then you would pay $120 * (1 - 20%) = $96 for the annual subscription.

.

So, the answer is 96
