    Answer:

    \large\boxed{1 t-shirt=7}

    \large\boxed{1 hat=3}

    Step-by-step explanation:

    Method:

    To work this out we would first need to find the difference between the contents of those two prices. in this case, it is 2 t-shirts.

    Now that we know the difference in the contents of both of them is 2 t-shirts, we can work out the value of 2 t-shirts. We can do this by subtracting the value of 17 from 31, this gives us 14. This means that the price of 2 t-shirts= £14.

    The next step is to work out the value of one t-shirt. We can do this by dividing the price of 14 by 2, this gives us £7. This is because the price of 2 t-shirts can be represted by 2t and so to work out the value of t we would need to divide 2t by 2.

    Now that we know the price of 1 t-shirt is £7, we can now work out the price of 1 hat. To do this we would subtract the price of 2 t-shirts, which is £14, from the end price of £17, this gives us £3. This means that the price of a hat is £3.

    Step by Step:

    1) Find the difference between the contents.

    2 T-shirts

    2) Subtract 17 from 31.

    31-17=14

    3)  Divide 14 by 2.

    14/2=7

    4) Subtract 14 from 17.

    17-14=3

    Answer:

    t shirt = £7

    hat = £3

    Step-by-step explanation:

    £31 – £17 = £14

    2 t shirts cost £14 so 1 t shirt costs £7

    now we know 2 t shirts cost £14 so £17 – £14 = £3

    a hat costs £3
