 Hello math learners! This is Mr. Marks, your friendly neighborhood math teacher. Remember, it's not just about getting the right answers, it's about learning and growing along the way. Now today's problem is coming to us from the Pennsylvania Department of Education's Algebra 1 2017 Keystone exam. This problem is an opportunity for us to hone our multiple choice strategies, so let's uncover the mysteries this problem holds together. First, it's a word problem, so let's give it a read. Mary measured the heights of two different plants every day. Plant A was one inch tall when Mary began her measuring, and it grew 0.5 inch per day. Plant B was three inches tall, and it grew 0.25 inch per day. On which day were plant A and plant B the same height? First off, don't worry, I know word problems can be pretty overwhelming, but let's remember to breathe, and let's do this together one step at a time. Help me out by rereading the problem. Do you recognize any particularly important numbers or statements we should make note of?
