Lilith originally had five dozen water bottles that she needed to sell at $2 each to get exactly enough money to buy her friend a birthday gift. However, at the store, Lilith realized she could not sell at $2 because the regular price was $1.85 per water bottle in her town, and she had to reduce her price to $1.85 as well to sell her water bottles. Calculate the total amount of money Lilith will have to find to buy her friend the birthday gift after selling her water bottles at the reduced cost.
Thoughts? Step-by-step reasoning:
Lilith had 5 dozen water bottles, and since a dozen has 12 water bottles, the total number of water bottles she had was 12 bottles / dozen * 5 dozen = 60 bottles. To buy her friend the birthday gift, Lilith originally had to sell her water bottles for a total of 60 bottles * $2 / bottle = $120. When she reduced the price to $1.85 to meet the regular price, the total amount of money she had from the sales was $1.85 / bottle * 60 bottles = $111. To buy her friend the birthday gift, Lilith has to find $120 - $111 = $9 more.
Thus, the answer is 9.
