susan marciano invested part of her $17,000 bonus in a fund that paid a 12% profit and invested the rest in stock that suffered a 4% loss. Find the amount of each investment if her overall profit was $120

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
