Class A did 1/4 of its sales and earned 26.92. When it does 4 quarters it will have 4 x as much money so A turns in 26.92 x 4. = $107.68
Class B turned in 38.25 when it did 1/2 of tis sales. When it does 2 halves it will have 2x as much money so B turns in 38.25 x 2 = $$76.50.
Class C turned did 3/4 of its sales and earned 62.38. When it does 1 more quarter it will have 4 x 62.38/3. That is 4 x 20.79 = $83.17 for them.
Adding those three numbers 107.68+76.50+83.17. It totals $267.35.
