    Answer: The number of shirts you can order = 40

    Step-by-step explanation:

    Let x = Number of shirts

    At T-Shirts R Us,

    Total cost = 50+1.50x

    At T-Shirt Planet,

    Total cost = 75+x

    As per given, when the cost at both companies is the same then

    1.50x+50=x+70\\\\\Rightarrow\ 1.50x-x=70-50\\\\\Rightarrow 0.50x=20\\\\\Rightarrow\ x=\dfrac{20}{0.50}=40

    Hence, the number of shirts you can order = 40
