Kayla is selling lemonade for $1 and cookies $0.50 outside of her house in order to earn enough money to buy a bike that costs $249. The number of cookies, C, that she sells is half the number of lemonade, L, that she sells.

Which system of equations matches the situation?

L + 0.50C = 249
L = 0.5C

L + C = 249
0.5L = C

L + 0.50C = 249
0.5L = C

L + C = 249
L = 0.5C
