Answer 2

Step-by-step explanation:

let the cost of hat be x

and the cost of t-shirt be y

now, according to question

7y+x= 67

x=67-7y...(1)

and other

5y+x=49

putting the value of equ(1)

5y+67-7y=49

-2y=49-67

-2y=-18

2y=18

y=18/9=2

putting the value of y in equ (1)

x=67-7y=67-7×2=67-14=53

therefore the cost of hat is £53

and the cost of t-shirt is £2
