Final answer:
The cost of each bracelet is $0.51.
Step-by-step explanation:
To find the cost of each bracelet, we need to calculate the total cost of the string and beads used for 1 bracelet and then divide it by the number of bracelets (500).
The cost of the string is $7 for 3 rolls. So, the cost of 1 roll is $7/3 = $2.33. Since each bracelet uses 12 inches of string, the cost of 12 inches of string is $2.33.
The cost of the beads is $12 for 2 bags. So, the cost of 1 bag is $12/2 = $6. Since each bracelet uses 24 beads, the cost of 24 beads is $6.
Adding the cost of 12 inches of string and 24 beads, the total cost of 1 bracelet is $2.33 + $6 = $8.33.
To find the cost of each bracelet if the string is 32 inches and there are 1000 beads, we can use the same calculations to find the cost of 32 inches of string and 1000 beads and divide it by 500.
The cost of 32 inches of string is (32/12) x $2.33 = $6.19. The cost of 1000 beads is (1000/24) x $6 = $250.
Adding the cost of 32 inches of string and 1000 beads, the total cost of 1 bracelet is $6.19 + $250 = $256.19. Therefore, the cost of each bracelet is $256.19/500 = $0.51.
