Objective 2 Solve using the five "Steps for Solving Applied Problems." See Example 2 In $2004,$ there were 7569 Starbucks stores worldwide. This is approximately $1681 \%$ more stores than 10 years earlier. How many Starbucks stores were there in $1994 ?$ (Round to the nearest whole number.) (wwwstarbucks, com)

Key Concepts

Percentage Increase

This concept involves determining how much a quantity has increased relative to its original value, expressed as a percentage. It is key to understanding how to transform a percentage change into a multiplicative factor that relates the original amount to the final amount.

Determining the Original Value from a Known Final Value

This involves setting up an equation where the final value is expressed as the original value multiplied by one plus the percentage increase (converted to a decimal). By rearranging this equation, the original value can be isolated and computed.

Structured Problem Solving Steps

This approach entails carefully following a series of systematic steps, such as understanding the problem context, identifying the given information, setting up the relevant equations, solving for the unknown variable, and verifying that the solution meets the problem's requirements. It is especially useful for multi-step real-world applications.

Rounding

Rounding is the process of approximating a number to the nearest whole number or other specified unit. This is important for presenting a clean, interpretable final answer, particularly when the context requires a whole number.
