Boomtown urban planners expect the city’s population to increase...
This problem can be solved most easily with the help of smart numbers. With problems involving percentages, 100 is typically the ‘smartest’ of the smart numbers.
If we assume that today’s population is 100, next year it would be 1.1 × 100 = 110, and the following year it would be 1.1 × 110 = 121. If this is double the population of one year ago, the population at that time must have been 0.5 × 121 = 60.5. Because the problem seeks the “closest” answer choice, we can round 60.5 to 60.
In this scenario, the population has increased from 60 to 100 over the last year, a net increase of 40 residents. To determine the percentage increase over the last year, divide the net increase by the initial population: 40/60 = 4/6 = 2/3, or roughly 67%.
For those who prefer the algebraic approach: let the current population equal p. Next year the population will equal 1.1p, and the following year it will equal 1.1 × 1.1p = 1.21p. Because the question asks for the closest answer choice, we can simplify our algebra by rounding 1.21p to 1.2p. Half of 1.2p equals 0.6p. The population increase would be equal to 0.4p/0.6p = 0.4/0.6 = 2/3, or roughly 67%.
The correct answer is D

Boomtown urban planners expect the city’s population to increase...
To experience significant growth in the coming years. With a booming economy and increasing population, urban planners predict that the city will face several key challenges and opportunities.
One major challenge will be managing the rapid population growth. As more people move to Boomtown in search of job opportunities and a high quality of life, the city will need to ensure that there is enough housing, transportation, and infrastructure to support the influx of residents. This may require the construction of new residential areas, the expansion of public transportation systems, and the improvement of roads and utilities.
Another challenge will be maintaining a balance between development and preserving the city's natural environment. Boomtown is known for its beautiful landscapes and outdoor recreational opportunities, and it will be important for urban planners to protect these assets while accommodating growth. This may involve designating green spaces and parks, implementing sustainable building practices, and promoting conservation efforts.
Additionally, urban planners will need to address issues of inequality and social inclusion within the city. As Boomtown grows, it will be essential to ensure that all residents have access to affordable housing, education, healthcare, and other essential services. This may require the implementation of inclusive zoning policies, affordable housing initiatives, and community development programs.
On the positive side, the growth of Boomtown presents several opportunities for urban planners to shape the city's future. They can work to create vibrant and diverse neighborhoods, foster a sense of community, and promote economic development. This may involve attracting new businesses and industries, supporting local entrepreneurs, and investing in cultural and recreational amenities.
Overall, Boomtown's urban planners have a challenging task ahead of them as they navigate the city's growth. However, with careful planning and strategic decision-making, they have the opportunity to create a thriving and sustainable city that meets the needs of its residents and preserves its unique character.
