1. Chandler checked the invoice. "Quite a mixed bag," he commented. "Weejees at 4 pounds and 7 pounds each, and then all those kumbits at 75 pence. I see you got 89 items in all." "That's right," Franklin told him. "It's funny, the total was exactly 89 pounds for the lot." How many of each did he buy?

5 weejees (2 at 7 pounds, 3 at 4 pounds), 84 kumbits

7 weejees (1 at 7 pounds, 5 at 4 pounds), 79 kumbits

9 weejees (3 at 7 pounds, 6 at 4 pounds), 71 kumbits
