<PRE><B>Question 1033550</B>
 A jewelry sells a necklaces for the cost of chain plus the cost of beads. Chain costs $20 each and beads cost $7.50 each. To which function family does the equation that best describes the cost of a necklace with x beads belong? 
Is it linear? 
----
Yes
intercept = the cost of the chain = $20
slope = incremental cost of beads = $7.50
Cost = 20 + 7.5b where b is the # of beads
