Gemma and Leah are both jewelry makers Gemma made 106 beaded necklaces Beia made 39 more necklaces and Gemma each necklace they make has exactly 104 for beads on it how many beads did both girls use altogether while making their necklaces

Both girls used 26104 altogether while making their necklaces:

Gemma would have used 11024 beads (106 x 104) to find how many beia made you would add 39 to 106 which equals 145, 145 x 104 = 15080. Now you add the amount of each girl used which would be 26104.
