Hightop roofing was $3765 in the "red" (owed creditors this amount) at the end of
june. at the end of december they were $8765 in the "red.” did they make or lose
money between june and december? how much?

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)
