5t-shirts and a hat costs £83.00,2 t-shirts and a hat costs £38.00.a)how much does a t-shirt cost?

$9 per t-shirt

Step-by-step explanation:

First you subtract the cost of the hats from the TOTAL cost of the the T-shrits and the hat.

$83.00-$38.00= $45

Now that you just have the shirts WITHOUT the hat, which is why we subtracted the $38.00, we have to devide. You devide 45 by the number of shirts.

45/5=9

$9 per T-shirt.

Hope this helps

i would say c is the best answer, hope it's right!

good luck! =)
