Hi Ryanzmw! :smile:

"She runs her washing machine every day" must mean once every day. :wink:

(it can't be less, and if it was more, the question would say so)

(if it said "she buys an apple every day", would you worry that it might mean that she buys several apples a day?)

you're going to have a hard time figuring out an output cost for this question since no input cost is given
