Alright this is the question and prompt. “Phone company A costs $0.15 per minute on a cellular device. Phone Company B costs $40 per month plus $0.05 per minute. The question is asking how to make an equation to set them equal. I know how to do that but I’m just unsure whether or not the $40 needs a variable or not
