Answer :
so lets take the cost of 1 T-shirt to be x
Since Amanda bought 6 t-shirts we can say the cost of 6 T- shirts is 6x
So the total cost of items = 55*2 +6x
[tex](55 \times 2) \: + 6x = 350 \\ 110 + 6x = 350 \\ 6x = 350 - 110 = 240 \\ 6x = 240 \\ x = \frac{240}{6} \\ x =40[/tex]
Ans: Each T-shirt is $40
