Answer:
3 packages will be required.
Step-by-step explanation:
Juanita puts 15 beads in a necklace.
Let Juanita purchases number of packages = 1
Then number of necklaces prepared = [tex]\frac{\text{Total number of beads}}{\text{Number of beads in one necklace}}[/tex]
= [tex]\frac{20}{15}[/tex]
From 1 package number of necklaces prepared will be 1 and number of beads left = 5
If she purchased 2 package then number of necklaces prepared = [tex]\frac{20\times 2}{15}=\frac{40}{15}[/tex]
From 2 packages 2 necklaces will be prepared and 10 beads will be left.
Now, if she purchases 3 packages of beads then number of necklaces prepared = [tex]\frac{20\times 3}{15}=4[/tex]
Therefore, 3 packages of beads will be required with no beads as left over.
