Mondemiete, Ikebukuro: ¥2,500 Plus ¥250 a Minute, Sixteen Times Out of Nineteen — and a 15% Card Fee That Comes Back on October 1
Mondemiete's twenty-cell price board looks like a wall of numbers and is actually one equation: a flat door charge plus ¥250 a minute, holding in sixteen of nineteen published prices. I solved the board, found the three cells that break it, priced every extension and coupon per minute, and then found the number that dwarfs all of it — a credit-card surcharge that is 15% for eleven months of the year and 0% until September 30.
