How much does a t-shirt cost?
How much does a hat cost?

Answer 1

T-shirt : £11

Hat : £7

Explanation:

Think of T-shirts as T

and Hats as H

5t + h = 62

2t + h = 29

we then subtract them both to cancel out h

3t = (62-29) = 33

now we divide 33 by 3 to find one t

33/3 = 11

so one t shirt is £11.00

now we substitute it back into the equation

2t ( 2x11 ) = 22

22 +h = 29

29 - 22 = 7
