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 59¢. Find the original cost of each puzzle if she spent a total of $27
Let X be the original cost of each puzzle.
Molly spent 6*X dollars on jigsaw puzzles.
Molly got a 6*X - $0.59 cents discount for each puzzle.
So each puzzle cost C = X - $0.59
So Molly spent a total of 6*C = $27.
Thus 6*(X - $0.59) = $27.
So 6*X - 6*$0.59 = $27.
So 6*X = $27 + 6*$0.59 = $27 + $3.54 = $30.54.
So X = $30.54 / 6 = $<<30.54/6=5.09>>5.09 per puzzle. Answer: \boxed{5.09}.
