Paul bought a soft and a sandwich for $9.90. what equation may be used to find the price of each item if the sandwhich cost 3.5 times as much as the soft drink

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)

It would take her 20 minutes.
