Define a variable ** Let w be the number of wet wipes Elsie had in the morning.
How many wet wipes did Elsie use throughout the day? ** Throughout the day, she used w-20 wet wipes.
How many wet wipes did Elsie refill the container with? ** Once that happened, she had to refill the container resulting in w-20+10 = w<<-20+10=-10>>-10 wet wipes.
How many wipes were in the container in the morning? ** By nighttime, she had w-10=60 wipes.
How many wipes were in the container in the morning? ** So then, w=60+10=<<60+10=70>>70.
How many wipes were in the container in the morning? ** She started with w=<<70=70>>70 wipes.
