Q. Sandy makes $2 profit on every cup of lemonade that she sells and $1 on every cupcake that she sells. Sandy wants to sell at least 5 cups of lemonade and at least 5 cupcakes per day. She wants to earn at least $25 per day. Show and describe all the possible combinations of lemonade and cupcakes that Sandy needs to sell to meet her goals. List two possible combinations.
Define Variables and Constraints: Define the variables and the constraints.Let L be the number of cups of lemonade Sandy sells.Let C be the number of cupcakes Sandy sells.Sandy makes $2 profit on every cup of lemonade and $1 on every cupcake.Sandy's goal is to earn at least $25 per day.Sandy wants to sell at least 5 cups of lemonade and at least 5 cupcakes per day.The constraints can be written as:L≥5C≥52L+C≥25
Minimum Lemonade Cups: Find the minimum number of lemonade cups Sandy needs to sell to meet the goal without selling any cupcakes.Since Sandy makes $2 profit on every cup of lemonade, we can calculate the minimum number of lemonade cups needed to reach $25 by dividing the goal by the profit per cup of lemonade.Minimum lemonade cups = $2$25 per cup = 12.5 cupsSince Sandy cannot sell half a cup, she needs to sell at least 13 cups of lemonade to meet the goal without selling any cupcakes.
Minimum Cupcakes: Find the minimum number of cupcakes Sandy needs to sell to meet the goal without selling any lemonade.Since Sandy makes $1 profit on every cupcake, we can calculate the minimum number of cupcakes needed to reach $25 by dividing the goal by the profit per cupcake.Minimum cupcakes = $1$25 per cupcake = 25 cupcakesSandy needs to sell at least 25 cupcakes to meet the goal without selling any lemonade.
Possible Combinations: List two possible combinations that meet the constraints.Combination 1: Sandy sells 5 cups of lemonade and the rest in cupcakes.Using the equation 2L+C≥25, we substitute L=5.2(5)+C≥2510+C≥25C≥25−10C≥15So, Sandy can sell 5 cups of lemonade and 15 cupcakes to meet her goal.Combination 2: Sandy sells 6 cups of lemonade and the rest in cupcakes.Using the equation 2L+C≥25, we substitute 2L+C≥251.2L+C≥2522L+C≥2532L+C≥2542L+C≥255So, Sandy can sell 6 cups of lemonade and 2L+C≥257 cupcakes to meet her goal.
