Answer:
The system of equations are
The reasonable price for pair of pants is $20.
Step-by-step explanation:
Let the price of shirt be 'x'.
Let price of pair of pants be 'y'.
Given:

framing in equation form we get;
Also Given:
Raheem purchased 3 shirts and 4 pairs of pants for 116.
So we can say that;
3 multiplied by the price of shirt plus 4 multiplied by the price of pair of pants is equal to 116.
framing in equation form we get;
Hence the system of equation are
Now by using elimination method we will subtract equation 2 from equation 1 we get;
Now Substituting the value of x in equation 1 we get;
Hence The reasonable price for pair of pants is $20.
