A necklace chain costs $15. Beads cost $2.75 each. You spend a total of $28.75 on a necklace and beads before tax. How many beads did you buy in addition to the necklace?

Calculate the amount left to spend on beads:
Bead Spend = Total Spend - Necklace Cost
Bead Spend = $28.75 - $15
Bead Spend = $13.75

Calculate the number of beads you bought:
Beads Bought = Bead Spend / Cost Per Bead
Beads Bought = $13.75 / $2.75
Beads Bought = $5
