Of the 60 people who were surveyed at Olivia's office, 70% spend an
average of $100 per week on groceries. Olivia works with 700 people.
She uses the equation 700 = 0.7x to determine how many of them would
spend an average of $100 a week on groceries. She finds that x = 1,000
people. Is Olivia's solution a reasonable prediction based on the survey
data? If not, find the correct answer.
