A website has no more than $15,000 to give away for a contest. They have decided to give away $1,000 twice a day every day until they have at least $3,000 left to award as a grand prize. How many days will the contest run?

If you would like to know how many days will the contest run, you can calculate this using the following steps:

x ... the number of days

every day: 2 * $1,000 = $2,000

$15,000 - $2,000 * x = $3,000

15,000 - 2,000 * x = 3,000

15,000 - 3,000 = 2,000 * x

12,000 = 2,000 * x

x = 12,000 / 2,000

x = 6 days

The correct result would be: The contest will run for 6 days until they have at least $3,000 left to award as a grand prize.
