Question

the members of the art club are making keychains that require 18 beads apiece. the art club adviser brought a bag with 250 beads for them to use. write an equation that shows how the number of beads remaining, y, depends on the number of keychains made, x. y =

Explanation:

Step1: Define total beads used

Total beads used for $x$ keychains: $18x$

Step2: Relate remaining beads to total

Remaining beads = total beads - used beads
$y = 250 - 18x$

Answer:

$y = 250 - 18x$
