A researcher has a budget of $1,000 to buy lab supplies. If each microscope costs $150 and each set of lab gloves costs $25, how many sets of lab gloves can the researcher buy after purchasing 3 microscopes?

In today’s evolving research landscape, scientists often face tight funding constraints while needing precise tools and protective gear. With lab supplies representing a key part of workplace expenses, many curious researchers calculate how to maximize their budget. A common question is: After purchasing 3 expensive microscopes, how many sets of lab gloves can remain within a $1,000 budget? This isn’t just a math problem—it’s a real scenario shaping daily lab operations across universities and private research centers in the U.S.

Why Lab Budget Planning Matters Now

Understanding the Context

Over the past few years, research funding has become more competitive, making it essential for scientists to manage budgets with precision. Equipment like microscopes—essential for clear, repeatable observations—typically commands $150 or more per unit. Meanwhile, lab gloves play a critical role in safety, infection prevention, and maintaining sterile environments, costing just $25 per set. Understanding how to allocate limited funds guides smarter procurement decisions, ensuring vital resources are used efficiently.

How the Math Works: Budget Allocation

Let’s break down the numbers. A researcher starts with $1,000. After buying 3 microscopes at $150 each:
