Throughout the day, she refills the container with 10 more wipes after using up 20. By nighttime, she only has 60 wipes left. How many wipes were in the container in the morning? 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. #### 70 One necklace is worth $34. Bob decided to buy one for his wife.
