y= 12.5x + 50


In the function y= 12.5x +50, y stands for weekly income, x stands for the number of hours that Tim works per week, and 50 is his weekly bonus. Because Tim gets 50 dollars no matter how many hours he works, there is no variable next to it. It is a constant.

His pay is determined by how many hours he worked. The coefficient of 12.5 is attributed to x because that is how much he earns per hour. y is the total weekly income based on his pay per hour multiplied by how many hours he worked plus the 50 dollar bonus.
