2 t-shirts and 3 hats costs £12.
5 t-shirts and 4 hats costs £23.
Find the cost of a t-shirt.
Find the cost of a hat.​

Answer 1

Explanation:

Suppose the cost of each t-shirt is x

and the cost of each hat is y

according to question

`\Rightarrow 2x+3y=12\quad \ldots(i)\\\Rightarrow 5x+4y=23\quad \ldots(ii)\\\text{solving (i) and (ii) we get}`

`x=3\ \text{and}\ y=2`

So, the cost of a t-shirt is £3

the cost of a hat is £2
