Question

Valentina purchased 200 beads for $48 to make necklaces. If she needs to buy 25 more beads, how much will she pay if she is charged the same rate? Answer in a complete answer.

Answer 1

200 beads cost $48
1 bead costs ($48/200)= $0.24
25 beads cost = ($0.24x25)=$6

For 225 bead she will pay ($48+$6)=$54

Answer 2

200 beads ----> $48
1 bead -------> 48/200=6/25
25 beads ----> 6/25 x 25 = $6
==> total charge: 48+6= 54
