Molly has 6 grandchildren. She likes to be fair and buy gifts for all of them at the same time. She found jigsaw puzzles, each discounted by 50¢. Find the original cost of each puzzle if she spent a total of $27.

The cost of each jigsaw puzzle is $27 / 6 = $<<27/6=4.5>>4.5.

Each puzzle is discounted by 50¢ so the original cost is $4.5 + 50¢ = $<<4.5+0.5=5>>5. Answer: \boxed{5}.

To find the original cost of each puzzle, we need to set up and solve an equation.

Let's assume the original cost of each puzzle is x dollars. Since Molly bought 6 puzzles, the total cost would be 6x dollars.

We know that Molly spent a total of $27, so we can write the equation:

6x = $27

To find the original cost of each puzzle, we need to isolate x.

Dividing both sides of the equation by 6 gives:

x = $27 / 6
x = $4.50

Therefore, the original cost of each puzzle was $4.50.
