Leon ordered 3 sets of toy organizers for $78 per set and 2 gaming chairs for $83 each. If there is a delivery fee that is 5% of the total sales, how much did Leon pay? Give me reasons, before answering the question
Three sets of toy organizers cost $78 x 3 = $234. Two gaming chairs cost $83 x 2 = $166. Leon's total orders amount to $234 + $166 = $400. Then, the delivery fee is $400 x 5 / 100 = $20. So, Leon had to pay a total of $400 + $20 = $420. So the final answer is 420.
