Answer:

$159.95

Step-by-step explanation:

Let price of trumphet be defined by $x$

price of clarinet = $139.95

Number of clarinets sold = 19

Earning through clarinets' sale = $19*139.95 = 2659.05$

Total earning of store = $4578.45

Earning through trumphets' sale = $4578.45 - 2659.05 = 1919.40$

price of one trumohet = $\frac{1919.40}{12} = 159.95$

price of clarinet = $159.95
