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. ______________________________________________________ Glad I could help, and good luck! _________________________ _________________________ _________________________
