Answer:
$19
Step-by-step explanation:
Let x be the cost of 1 shirt
Cost of 2 shirts = 2x
Let y be the cost of 1 pant
Cost of 3 pants = 3y
Cost of 2 pants = 2y
Since we are given that James bought two shirts and three pairs of pants for $87.
So, Equation becomes: --1
Now we are given that Matthew bought two pairs of pants and one shirt for $53.
So, Equation becomes: --2
Now substitute value of x from 2 in 1
Cost of 1 pant is $19
Substitute the value of y in 1 to get value of x
Cost of 1 shirt is $15
Hence one pair of pants costs $19.
