Feasible options 8-30, pages 6, 7, items 13, 16

Item 13:  100 (t) + 40 (m) < or = 1360

Try t = 0 to find easy point (0, m)
Then try m = 0 to find easy point (t, 0)

When t = 0,   40 (m) = 1360,  so m = 34
When m = 0,   100 (t) = 1360, so t = 13.6

The easy points are (0, 34) and (13.6, 0)
Plot these point on the grid in item 16, and connect the dots with a line.
