Question: Youngsville had a population of 684 people. The town had a growth spurt and the population increased by 25% then they witnessed that 40% of the population moved away. What is the current population? Think carefully first, then make a decision:
The town had 684 people then had a 25% growth spurt increasing the population by 684 * .25 = 171 people. The town had 684 people then they added 171 people bringing the population to 684 + 171 = 855 people. There were 855 people and 40% moved away so it decreased by 855 * .40 = 342. The population was 855 and 342 people moved away making the new population 855 - 342 = 513 people. So the answer is 513.
