A museum curator is digitizing a collection of 120 historical microscopes. If 30% are compound microscopes, 45% are adjustment-type models, and the rest are stereo microscopes, how many stereo microscopes are in the collection?

A museum curator is digitizing a collection of 120 historical microscopes, revealing fascinating insights into the evolution of optical instruments. With growing interest in preserving scientific heritage and making rare technology accessible, this digital initiative reflects a broader trend of museums leveraging technology to share rare collections with global audiences. The collection includes three main types of microscopes, each playing a distinct role in shaping early microscopy. ### Why This Digitization Initiative Is Gaining Attention In today’s digital age, curiosity about scientific history has surged, particularly around tools that powered centuries of discovery. Museums across the United States are embracing digitization to preserve fragile artifacts, expand public access, and engage new generations. A project spotlighting 120 historical microscopes taps into this momentum, offering a behind-the-scenes look at how these instruments evolved—from early compound models shaping early cell research to precision adjustment-type designs enabling fine observational work, and stereo microscopes revealing depth and dimension in microscopic detail. ### The Composition of the Collection: Where Stereo Microscopes Fit
