The cost of one shirt is 12.50 and cost of one pair of jeans is 24.75
Step-by-step explanation:
Let,
Cost of one shirt = x
Cost of pair of jeans = y
According to given statement;
4x+3y=124.25 Eqn 1
3x+5y=161.25 Eqn 2
Multiplying Eqn 1 by 3

Multiplying Eqn 2 by 4

Subtracting Eqn 3 from Eqn 4

Dividing both sides by 11

Putting 24.75 in Eqn 1

Dividing both sides by 4

The cost of one shirt is 12.50 and cost of one pair of jeans is 24.75
