Answer 1

67.3%

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 =
`(profit)/(cost)` × 100%

=
`(942)/(1400)` × 100% ≈ 67.3% ( to 1 dec. place )
