Let the musical store sells 'x' number of trumpets and 'y' number of clarinets.
According to question,

..............(1)
Also given Trumpets cost $149 and clarinets cost $99.
then the shop sold x trumpets for $149x and sold y clarinets for $99y and total sales were $3233.
thus, ...........(2)
Solving for equation (1) and (2),
Multiply equation (1) by 149 , we get
(1) ⇒ ........(3)
Now, subtract equation (3) from equation (2) , we get
Thus, number of clarinets musical store sold was 15.8 but since clarinets are to be in whole number rounding off to the nearest integer 16.
and put y = 16 in (1) , we get
Thus, number of trumpets musical store sold was 11.
