Question

Sydney is making bracelets three bracelets require 21 beads the number of bracelets varies directly with the number of beads write an equation in the form of Y equals a X then find the amount of beads needed for 32 bracelets

Answer 1

Y = kx

21 = k(3)

k = 7

7 beads per braclet

y = 7x

x=32 ---> y = 7*32 = 224

Answer 2

If 3 bracelets need 21 beads, then there are 7 beads to a bracelet (3x=21, x=7). So 32 bracelets, at 7 per is 224 (7*32=224).
