Worth of sweatshirts were sold. How many of each color were​sold?

Time for some algebra.

What do YOU think as we wont do the work for you ?!

Firstly, you need to learn to format

so w*11.95 + y*11.50 = 337.55
w + y = 29

28 white sweatshirts were sold at $11.95 and one was rung up wrong for $2.95 for a total of $337.55. No one buys yellow sweatshirts.
