Answer:
$(3b+2)
Step-by-step explanation:
The cost of making b bracelets = 4+5b
The cost of making b necklaces = 8b+6.
To determine how much more it cost to make b necklaces than b bracelets, we simply subtract.
Extra Cost = Cost of b Necklaces-Cost of b Bracelets
=(8b+6)-(4+5b)
open the brackets
=8b+6-4-5b
Collect like terms
=8b-5b+6-4
=3b+2
It costs $(3b+2) more to make b necklaces than b bracelets.
