Gemma and leah are both jewelry makers. gemma made 106 beaded necklaces. leah made 39 more necklaces than gemma.
a. each necklace they make has exactly 104 beads on it. how many beads did both girls use altogether while making their necklaces?
b. at a recent craft fair, gemma sold each of her necklaces for $14. leah sold each of her necklaces for $10 more. who made more money at the craft fair? how much more?

Gemma made $34 more than Leah.

Step-by-step explanation:

Gemma made number of beaded necklaces = 106

Leah made 39 more necklaces than Gemma.

Leah made number of beaded necklaces  = 106 + 39 = 145

a. There are 104 beads on each necklace.

The total number of beads used altogether

= (106 × 104) + (145 × 104)

= 11,024 + 15,080

= 26,104

b. Gemma sold her 106 necklaces for = $14

Total price of her necklaces = 106 × 14

                                               = $1,484

Leah sold her 145 necklaces for = $10

Total price of her necklaces = 145 × 10

                                               = $1,450

Difference in Gemma and Leah's amount = 1484 - 1450 = $34.00

Therefore, Gemma made $34.00 more money than Leah.
