How am I supposed to solve this?

"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."

maximize p = profit = 2 L + 1 C >/= 25

L >/= 5
C>/=5

start with L = 5
10+C >/= 25
C >/= 15

if L = 6
12 + C >/= 25
C >/= 13
so
L 7, C 11
L 8 ,C 9
L 9 , C 7
L 10, C 5
are your MINIMUM combinations. Of course you can always sell more

I apologize, but I still don't understand.
Answered by Damon
You had to have at least 5 L or lemonade
so I started there
to get $25 I needed at least 15 cupcakes
every time I added a lemonade, I needed two less cupcakes
until finally I got to 10 lemonades and 5 cupcakes
I had to have at least 5 cupcakes, so there it ended
