you decide to buy a board game to play. The cost of the game is between $10 and $20, and it is not a whole dollar amount.

Decide the cost of the board game. Write it here:

$15.50

To determine the cost of the board game, we need to find a decimal number between $10 and $20 that is not a whole dollar amount.

Let's list out some possible values within this range that fit the criteria:

$10.01
$10.50
$11.75
$12.99
$13.25
$14.50
$15.90
$16.75
$17.60
$18.99
$19.25

One of these values can be chosen as the cost of the board game.

To determine the cost of the board game, we need to find a decimal number between $10 and $20. Since the cost is not a whole dollar amount, we should consider numbers with cents.

To start, let's find the decimal number that is halfway between $10 and $20. We can calculate this by adding $10 and $20 and then dividing the sum by 2.

$10 + $20 = $30
$30 รท 2 = $15

So, $15 is the decimal number that is halfway between $10 and $20.

However, since the cost is not a whole dollar amount, we can choose a number slightly higher or lower than $15.

For example, you could decide on $14.99, which is slightly lower than $15. Alternatively, you could go with $15.01, which is slightly higher than $15.

Ultimately, the decision of the exact cost within the given range is up to you!
