Answer 1

Answer:

67.3%

Step-by-step explanation:

Calculate profit = selling price - cost price

cost price = 50 × $28 = $1400

38 × $49 = $1862

12 × $40 = $480

selling price = $1862 + $480 = $2342

Profit = $2342 - $1400 = $942

% profit = $\frac{profit}{cost}$ × 100%

             = $\frac{942}{1400}$ × 100% ≈ 67.3% ( to 1 dec. place )
