Materials = $4.25
Labor = $5.35
Sale Price = $16.99

A.) Profit = Sale Price - (Materials + Labor)
Profit = 16.99 - (4.25 + 5.35)
Profit = 16.99 - (9.60)
Profit = $7.39

Profit / Sale Price = % Profit
7.39 / 16.99
or
739 / 1699

B.) % Profit = Profit / Sale Price × 100
  % Profit = 7.39 / 16.99 × 100
  % Profit = 0.43496 × 100
  % Profit = 43.496 %
  % Profit = 43 %

C.) Total Sales = $324.86

Necklaces Sold = Total Sales / Individual Sale Price
Necklaces Sold = 324.86 / 16.99
Necklaces Sold = 19.12

**This question is absolutely ridiculous because either she made money from tips or someone either paid too much or too little**

Total Profit = Necklaces Sold × [Sale Price - (Materials + Labor)]
Total Profit = 19 × [16.99 - (4.25 + 5.35)]
Total Profit = 19 × (7.39)
Total Profit = $140.41

OR

Total Profit = 20 × (7.39)
Total Profit = $147.80
