A Science book and a Fiction novel are available from a wholeseller. Each costs an integer number of dollars. The cost of 620 copies of the Fiction novel is greater than that of 340 copies of the Science book but less than that of 341 copies of that book.

Would $700 be enough for a retailer to purchase 11 copies of the Science book and 5 copies of the Fiction novel?

CLS
FOR s = 1 TO 200
 low = 340 * s + 1: high = 341 * s - 1
 highF = INT(high / 620)
 lowF = -INT(-low / 620)
 IF highF >= lowF THEN
   FOR f = lowF TO highF
    PRINT f; s; 11 * s + 5 * f,
   NEXT
   PRINT
 END IF

105  191  2626

so nothing less than 701 will do.
