$8000 was borrowed from two sources, one that charges 12% simple interest and the other that charges 10% simple interest. If the total interest at the end of 1 year was $920., how much money was borrowed from each source?

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
