Aboutique sold $127.50 worth of purses. how many purses did they sell? they sell for $7.50 each

They sold 17 purses. 127.50 divided by the 7.50 is 17, which is the amount of purses

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)
