How much does a hat cost

Answer 1

a T-shirt costs £5

a hat costs £2

Explanation:

Suppose

A T-shirt=x

A Hat=y

So the equation is

8x+y=42

3x+y=17

So

8x+y=42

3x+y=17

------------

5x=25

x=5

So a T-shirt costs £5

3.5+y=17

15+y=17

y=2

So a hat costs £2

Answer 2

t-shirt: £5

hat: £2
