Last month's puzzle February/10)
Last summer I needed some lumber for a deck railing project - 2 x 4's at $6.50 each and 2 x 6's at $8.50 each. My neighbour, who has a large pickup truck, offered to pick it up for me, and I gave him $150 to make the purchase. When he came back with the lumber he gave me $20 back as change. Unfortunately, he had reversed the numbers of each category of lumber that I needed.
(For the purpose of this puzzle, please suspend any disbelief regarding the prices, and pretend I live in a paradise where there are no sales taxes.)
How much should he have paid to get the correct numbers of each?
$110.00
