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
[tex]1.50x+50=x+70\\\\\Rightarrow\ 1.50x-x=70-50\\\\\Rightarrow 0.50x=20\\\\\Rightarrow\ x=\dfrac{20}{0.50}=40[/tex]
Hence, the number of shirts you can order = 40
