Final answer:
Jaden made $100 from his lemonade and cookie stand by selling 40 cups of lemonade at $1 each and 20 cookies at $3 each.
Step-by-step explanation:
Jaden wants to know how much money he made by selling lemonade and cookies. Jaden sold lemonade at $1 per cup and cookies at $3 each. To calculate the total money made from the lemonade, we multiply the number of cups sold by the price per cup: 40 cups × $1 = $40. To calculate the total money made from the cookies, we multiply the number of cookies sold by the price per cookie: 20 cookies × $3 = $60.
Now we add the totals from lemonade and cookies to find the overall total money Jaden made: $40 + $60 = $100.
Therefore, Jaden made a total of $100 from his lemonade and cookie stand.
