Please help I need answer Maria began the school year with $200 in her school lunch account. The amount of money in the account has decreased linearly. After 3 months, she had $155 in her account. After 5 months, she had $125 in her account. Which function models the amount of money that Maria has in her account at the end of n months? f(n) = 200 - 15n O f(n) = 30n - 200 f(n) = 200 - 30n O f(n) = 15n - 200​
