How many ways to make 75?

To determine the number of ways to make 75, we need more context. Are we looking at different combinations of numbers, or are we considering factors or multiples of 75? If we are looking at combinations, we could use a partition function or dynamic programming to calculate the number of ways. If we are considering factors or multiples, we would need to find all the factors of 75 and calculate the combinations from there.
