Using the numbers [40, 80, 24, 25], formulate an equation that reaches 107. You can use basic arithmetic operations (+, -, *, /) and each number should appear only once in your solution. Showing your step-by-think process in <think> </think> tags and the final equation in <answer> </answer> format. For example <answer> (20 + 25) * 2 = 100 </answer> (Correct! Now, add 4 more to reach the target.)<|im_end|>
