£9.00

Step-by-step explanation:

67.00-49.00 = 18.00÷2 = 9.00

Let's Try:

a) 9.00×7 = 63.00+4.00(hat) = 67.00

b) 9.00×5 = 45.00+4.00(hat) = 49.00

Answer 2

Answer:

tshirt equals £9

and hat equals £4

Step-by-step explanation:

7t + h = 67

5t +h  = 49      subtract bottom eq from top

 

2t = 18      t = 9

 

5(t) + h = 49

5(9) + h = 49

45 + h = 49

h = 4
