Preparing for the next class

In the next in-class activity, you will need to know how to interpret the meaning of

percents, calculate and estimate percents, and answer questions about the 100

Thousand Lives Campaign.

Questions 1–5: A foodborne illness is an illness that a person gets from eating food that

has spoiled or been contaminated in some way.

1) In industrialized countries, such as the United States, up to 30% of the population

suffers from foodborne illnesses each year. This means that 30 out of 100 people

living in industrialized countries will likely suffer from foodborne illnesses each

year.

2) In 2019, the total population was about 330 million people. Using the estimate from

Question 1, how many of these people suffered from a foodborne illness that year?

99,000,000

3) In 1994, an outbreak of illness occurred in the U.S. due to ice cream contaminated

with salmonella (a bacterium). The outbreak affected an estimated 224,000 people.

If the total population in the United States at that time was 260,000,000, which is

the best estimate for the percent of people who were affected?

a) About 0.1%

b) About 1%

c) About 5%

d) About 10%

e) About 25%

4) Complete the following statement: The 1994 salmonella outbreak affected

approximately 86 out of every 860 people in the United States.

5) A report about foodborne illnesses indicated, “About 1 egg out of every 20,000

contains salmonella inside the shell.” This statement means that which of the

following is true?

a) 0.005% of eggs contain salmonella.

b) About 1% of eggs contain salmonella.

c) More than 1% of eggs contain salmonella.

d) Approximately 50 out of every 100,000 eggs contain salmonella.

6) About 16% of drivers are uninsured. There were approximately 222 million drivers

in the United States in 2017.

How many of these drivers were likely uninsured?

a) 35,520

b) 35,520,000

c) 355,200,000

d) 3,552,000,000

7) The regular price of a digital camera is $350. The store marks the camera 30% off

its regular price. What is the new price for the digital camera?

a) $320

b) $338.40

c) $105

d) $245

8) In 2011, Germany had an outbreak of illness caused by the bacterium called E.

coli. As of June 15 of that year, 3,235 people in Germany had become sick and 36

had died.

What percent of those who got sick also died? Round your answer to

the nearest tenth of a percent. 1.1%

9) A ventilator is a device that helps control breathing in patients. Hospitals use

ventilators to save lives, but using a ventilator runs the risk of introducing an

infection. The lower range of the number of cases of ventilator-associated

pneumonia developed in U.S. hospitals is 250,000 cases per year.

The rate of

patient death associated with these cases varies, but suppose 36,000 of these

cases in a given year were associated with patient death. What percent of
