Ed spent 8.5% of his savings on lunch, which costs $5.25. how much did he have in savings before lunch?

Copy down the attachment on paper. Use this to cross multiply: multiply 5.25 by the 100, then divide by 8.5 to get your x value, which will be $61.76 (rounded to the nearest hundredth if calculated, since cents only goes to that place). I hope this helped!
