$1700 @ 15% interest is $255. It doesn’t say if that’s monthly (probably) or weekly (unlikely, but the world is cruel enough that it’s very possible). At a minimum wage job in America at the time was $5.15 /hr. If you worked 40 hours a week (and it’s unlikely they had it this easy) they would make $206 /wk before taxes (however that works for illegals) but let’s say it’s $175 /wk X 4 = $700 – $255 = $455 /mo.
