A 14 pound mixture of pineapple cost 3.10. The mixture of the pineapples is made of a combination of two types. How many pounds of each pine apple were used

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)

Add the cents that add the left overs to get the first number

The answer would be 5< 6n
