Lesley purchased 5 beads at a total cost of 80 cents. The round beads cost 15 cents each, and the oval beads cost 20 each. The equations and graph below can be used to determine the number of each type of bead kesley purchased. Where x represents the number of round beads and y represents the number of oval beads

Lesley purchased 1 oval bead and 4 round beands.

Step-by-step explanation:

Given that Lesley purchased 5 beads at a total cost of 80 cents, and the round beads cost 15 cents each, and the oval beads cost 20 each, to determine what are the numbers of round and oval beads Kelsey purchased, the following calculation must be performed :

5 x 0.20 + 0 x 0.15 = 1

4 x 0.20 + 1 x 0.15 = 0.95

2 x 0.20 + 3 x 0.15 = 0.85

1 x 0.20 + 4 x 0.15 = 0.80

Therefore, Lesley purchased 1 oval bead and 4 round beands.
