The price of one hat is $2 and price of one pair of mittens is $5.
Step-by-step explanation:
Let,
Price of one hat = x
Price of one pair of mittens = y
According to given statement;
5x+4y=30 Eqn 1
2x+3y=19 Eqn 2
Multiplying Eqn 1 by 2
Multiplying Eqn 2 by 5
Subtracting Eqn 3 from Eqn 4
Dividing both sides by 7
Putting y=5 in Eqn 1
