Please help me. My math teacher gave us the classwork and homework and they were both different lessons. She said that the homework was worth 100 points and it's due tomorrow and I am really confused.
K = number of races than Kelly ran
Ana ran 18 races. The information in the problem statement translates into algebra as
18 = 2K - 4
Solve for K.
18 + 4 = 2K
22 = 2K
K = 1
Kelly ran 11 races.
