Mrs. Davis bought 6 pounds of grapes for $18 at this rate how much would 4.5 pounds of grapes have cost?

Check the internet ok that will

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)

The correct answer is $90
