“The Cost-Effective Choice: 10-Year Lithium Ion Smoke Detectors vs. 9V Battery Smoke Detectors”

I need a visual aid for my persuasive speech that I have to record at home for my online public speaking class. I will more than likely print the powerpoint out and place it on a posterboard to be used during my recording of my speech at home. I will attach my whole speech outline, however I just want slides created for my second main point in the outline, the cost analysis of smoke detectors with 9v batteries versus 10 year lithium ion batteries. I am looking for the slides to be simple but catchy overall, including pictures of the smoke detectors, spare batteries, and the cost analysis information i have provided in the outline. I would like the cost analysis data to be summed up well so it is not too wordy on each slide. I want the slide to show the cost of each style smoke detector, cost of spare batteries, and the 10 year savings that occurs when buying the 10-year lithium ion style smoke detector compared to the 9v standard smoke detector. I have highlighted the content for reference of the slides in red on my outline. I also am attaching smoke detector photos and battery photo of the models i am speaking to for pricing in the speech.
