Hi there,
I have the homework problem "Someone spilled ink on a bill for 36 sweatshirts. If only the first and last digits were covered and the other three digits were, in order, 8, 3, 9 as in ?83.9?, how much did each cost? Other than arbitrarily plugging in numbers, I have no idea how to figure this out. I guessed 183.96 because divided by 36 is 5.11, which is a nicer decimal that most of the ones I'd been getting. However, I have no way of knowing if that's right. Is there a formula behind this? Thanks for your help!
