You are an urban planner assessing the growth of a city. Ten years ago, the city's population was 249,583. Its current population is 318,270. By about what percentage has the city grown over the past ten years?

27.52 percent

Step-by-step explanation:

Percentage increase = (new - original) / original * 100

new = 318270

old = 249583

Substitute in what we know

percentage increase = (318270-249583) / 249583 * 100

= (68687/249583) * 100

.275207045*100

27.5207045 percent
