Answer: $7.
Step-by-step explanation:
It is given that the printing company charges a certain amount for each shirt plus a setup fee of $40.
Let x be the cost of each t-shirt.
There are 21 students in the drama club. So, total cost of 21 t-shirts is
[tex]\text{Total cos}=40+21x[/tex]
It is given that the t-shirt order costs a total of $187.
[tex]40+21x=187[/tex]
[tex]21x=187-40[/tex]
[tex]21x=147[/tex]
Divide both sides by 21.
[tex]x=\dfrac{147}{21}[/tex]
[tex]x=7[/tex]
Therefore, the cost of each t-shirt is $7.
