To find the unit rate for the T-shirts: you divide the $150 by the number of T-shirts. 150/50 = 3 50/50 = 1 Therefore, one T-shirt = $3 Do the same with the rest: $3/shirt $4.43/video game 6 tablespoons of sugar/glass of cocoa cola Hope that helps! P.S. I don't know what you mean when you say to write an equation but hopefully you can still figure it out!
