4 Liam is trying to build an emergency fund. For planning purposes, he developed two functions, L(t) and M(t), that determine the least amount and most amount, respectively, of money (in dollars) in any given month contributed to the emergency fund (with t = 0 corresponding to April). What can he reasonably conclude if L(3) = 1,500 and M(3) = 2,500? In July, he will have contributed between $1,500 and $2,500 to his emergency fund. In July, he will have contributed $1,000 to his emergency fund. He will contribute more money in July if he uses M(t) instead of L(t). He cannot contribute more than $1,500 in July, but he can contribute up to $2,500 after July.
