You are shopping for a new printer to take back to college with you. you decide on the pixma ip100 due to its superior photo print quality and are now looking for the best price. different stores have different deals, plus the manufacturer was offering a $30 mail-in post-purchase rebate. you determined from the canon website that the msrp for the printer was $299 but one online store had it listed for $279. that price included free shipping, which you figured was at least a $20 savings. in addition, the seller included a usb cord necessary to connect the printer to your laptop, which was priced at $25 on canon's website. while the online store paid for shipping, there was a $5 fee to insure the printer during shipping. the online store did take trade-ins of old printers, but you didn't have any used printers to trade anyway. finally, the online store offered a special holiday coupon on this printer that was good for an additional $10 off the price of the printer. assuming that the store's cost for the printer and the usb cord was 50% of its list price and that shipping was set at its cost, what were the seller's costs for this transaction? a) $172b) $152c) $164.50

answer///video, because samuel can show his work in real time and be better understood;

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
