Part A:
c = $3 (cost per necklace) × 8 (number of necklaces sold) ÷ 4 (number of books)
c = $24 ÷ 4
c = $6
Part B:
To buy 9 charms at $2 each, Sandra would need to earn 9 × $2 = $18.
Since Sandra earns $3 for each necklace she sells, she would need to sell $18 ÷ $3 = 6 necklaces.

Therefore, Micah spent $51 in all.

- Kelsey bought 4 packages of pencils and 3 packages of markers.
- Kelsey spent $4 on pencils.
- Kelsey spent more on the pencils than she spent on the markers.

u sure
Apologies for the confusion earlier. Let's calculate the total amount spent by Kelsey:
Kelsey bought 40 pencils at a cost of $2 per package. Therefore, Kelsey spent 40/10 * $2 = $8 on pencils.
Kelsey bought 24 markers at a cost of $4 per package. Therefore, Kelsey spent 24/8 * $4 = $12 on markers.
The total amount spent by Kelsey is $8 + $12 = $20.
So, the correct statement is:
- Kelsey spent $20 in all.
