Molly has 6 grandchildren. She likes to be fair and buy gifts for them all at the same time. She found jigsaw puzzles and each were 50 cents off. Find the original cost of the puzzles if she spent 27 dollars total
If the puzzles were each 50 cents off then the original price is 0.5+x where x is the sale price
So she spent 6*(0.5+x) = $27
So 0.5+x =27/6 = $<<0.5+27/6=5>>5
The original cost was 0.5+5 = $<<0.5+5=5.5>>5.5. Answer: \boxed{5.5}.
