Question

Hou has set a goal to bake 150

Answer 1

So a basic function is y=mx+b where m is a rate and b is the constant. His goal is 150 so y is 150 and the rate of his baking is 16 so m is 16, finally he has already 22 done so 22 remains constant. Plugging all these in you should get the following equation:

150=16x+22
