The have ordered 36 blue T-shirts.
___________________
How I got it --- So, we take away 16 from 58. You get 42.
________________________________________
So, from then, you know 36 is 6 times as many as 6, right? ( Because 6 x 6 = 36)
___________________________________________________________
So, then, you have ordered 36 blue shirts and 6 white shirts, because 36 + 6 =42.

Answer:
a. 30
Step-by-step explanation:
(f.f) = f(f(x))
Given: f(x) = x^2 -x
Now replace x = x^2 -x in f(x), we get
(f.f) = f((x^2 - x)^2 - (x^2 - x))
= (x^2 - x) (x^2 - x) -x^2 + x
= x^4 -x^3 - x^3 + x^2 - x^2 + x
= x^4 -2x^3 + x
Now plug in x = 3
f.f(3) = 3^4 -2(3)^3 + (3)
= 81 - 2*27 + 3
= 81 -54 + 3
f.f(3) = 84 -54
(f.f)(3) = 30
Thank you.
