This one is for James, in spite of him calling lifts elevators, which I have so tried to correct and failed to do with a great niece. At least James after a bad start did start calling them lifts.
I've brought my 1980s solar powered Casio in from the recharging sunlight and hopeful its calculations will be correct. It was hot today and it may be overcharged. I've prepared in advance to blame the calculator for mistakes.
There is a serious discordance with the carrying capacity of lifts. Oh, I've just realised I am going to have convert these to pounds as well.
1275 (how do I make a divide symbol?) :/ 17 = people weighing 75 kg, 165 pound.
