Amy got a $1,000 loan from her bank, and she had to repay $1,550. what are the principal and interest amounts in this transaction? principal is $1,000; interest is $1,550 principal is $1,550; interest is $550 principal is $1,000; interest is $550

C. principal is $1,000; interest is $550 :D

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)
