The museum curator is preparing a digital exhibit on early computing devices. She finds that the number of vacuum tubes in ENIAC is 50% more than in EDVAC. If EDVAC had 17,500 tubes, how many vacuum tubes does ENIAC have?

["The Historical Significance of Vacuum Tubes in Early Computing: A Deep Dive by the Museum Curator", "When exploring the evolution of early computing, one fascinating detail stands out: the sheer size and complexity of vacuum tube-based machines. Recently, the museum curator behind a groundbreaking digital exhibit on early computing devices uncovered a key insight into the ENIAC (Electronic Numerical Integrator and Computer), revealing how its vacuum tube count dramatically surpassed that of its successor, EDVAC (Electronic Discrete Variable Automatic Computer).", "According to historical data, EDVAC utilized exactly 17,500 vacuum tubes. Curators have found that the number of vacuum tubes in ENIAC is precisely 50% greater than in EDVAC. This percentage increase reflects ENIAC’s ambitious engineering and oversized architecture, designed to perform complex calculations during World War II.", "To calculate ENIAC’s vacuum tube count, we start with EDVAC’s 17,500 tubes and apply a 50% increase. This is done by multiplying 17,500 by 1.5 (which corresponds to adding 50% more tubes):", "[\n\ ext{ENIAC tubes} = 17,500 \ imes 1.5 = 26,250\n]", "Thus, ENIAC contained 26,250 vacuum tubes—a staggering number that underscores the mechanical and technological leap required to achieve electronic computation at scale.", "This distinction not only highlights the exponential growth in hardware complexity during the 1940s but also emphasizes the remarkable ingenuity of engineers who built ENIAC. The museum’s digital exhibit brings this story to life, helping modern audiences grasp the monumental scale of vacuum tube technology and its pivotal role in computing history.", "As the curator prepares this immersive online experience, visitors will gain a clearer understanding of early computing’s foundations—where vacuum tubes, not transistors, powered groundbreaking innovation. For tech historians and enthusiasts alike, this data spotlight reveals how quantity and capacity in early hardware set the stage for the digital revolution.", "---", "Explore our digital exhibit now to discover more about EDVAC, ENIAC, and the vacuum tube era—the true which inspired the future of computing."]
