 <translate> First find the number of weeks Casey stays: 3 months * 4 weeks / month = 12 weeks. Then multiply that number by the weekly rate to find how much she would pay weekly: 12 weeks * $280 / week = $3360. Then multiply the number of months she stays by the monthly rate to find how much she pays monthly: $1000 / month * 3 months = $3000. Then subtract that number from the total amount she pays if she pays weekly to find her savings: $3360 - $3000 = $360. The final answer: 360. <yor> Àkọ́kọ́, wádìí iye ọ̀sẹ̀ tí Casey fi wà nílé: oṣù mẹ́ta * ọ̀sẹ̀ mẹ́rin / oṣù = ọ̀sẹ̀ méjìlá.
