She only needs to sleep half as much as a normal human would, so a late bedtime is no concern of hers. She lights a lamp, and stays up counting her money.
Seventeen OTC gold coins. One fifty-sovereign steel-and-glass coin. Twelve five-sovereign coins. Four one-sovereign coins. Three shillings. Two five-pence coins. At a rate of eighty-seven sovereigns to the OTC gold coin, that works out to… one thousand, five hundred and ninety-three sovereigns, three shillings, ten pence.
She doesn't want to sell more of the gold this soon if she can help it, so that puts the vast majority of her funds off-limits. Minus one thousand, four hundred and seventy nine sovereigns. What does she have left in native currency? One hundred and fourteen sovereigns, three shillings, ten pence. Alright. Reserve seventy-five sovereign for her eventual trip to London; That leaves her with thirty-nine sovereign and change. It costs four sovereign a week to live here and another two and a bit per week for groceries. She also would like singing lessons. She has no idea how much that would cost but five sovereign a week surely ought to cover it. So that's eleven sovereign a week, letting her stay for three further weeks before she'd have to go, but there's no fun budget there. So call it 15 sovereign a week and she has roughly another two weeks after this one.
If she keeps to that, then can she afford an engine? A thousand sovereigns is definitely "sell all of her gold" money. There are four jewellery stores in town. She can sell five coins at each of the remaining three stores and have… fifteen times ninety… One thousand three hundred and fifty sovereigns, slightly less than. A lot depends on the exact cost of an engine, but it is definitely within reach if it's near Lenora's estimates. Supplies, crew… Charts. Charts could definitely be worth something. Call it ten crew, each paid… ten sovereign? She doesn't know enough yet.
So, information. She can look at the wholesaler's prices tomorrow and see what food and fuel cost. She can ask around the rail yards for a better price on a locomotive. She can just purchase a chart or two, they'd be useful to her even if she never boards another engine again. She can ask about signing on to an engine and the average wage of a crewmember. Lenora would know that, but how best to ask? Hm.
She checks the clock again.
