Answer 2

The cost of 1 t-shirt is £ 1

The cost of 1 hat is £ 5

Step-by-step explanation:

let the cost of 1 tshirt is  t

cost of 1 hat is h

then according to the question

7t + 5h = 32...(1)

3t + 4h = 23 ..(2)

solving 1 and 2 by elimination method

multiplying equation 1  by 3 and equation 2 by 7 we get

21 t + 15 h = 96

21t + 28 h = 161

subtracting

we get

- 13 h = -65

h = 5

then put the value of h in equation 1

7t + 5h = 32

7t + 5(5) = 32

7t + 25 = 32

7t = 32 - 25

7t = 7

t = 1

hence , The cost of 1 t-shirt is £ 1

The cost of 1 hat is £ 5
