A city bus company requires exact change or a token to ride a bus. The company
conducted a random survey of 100 passengers to determine how they paid their bus
fare. The survey results are shown in the table below.
Complete the following in the Answer Book:
- Last week 2,000 passengers rode the bus. Based on this survey, how many of
these passengers would be expected to use exact change to pay the bus fare? Use
mathematics to explain how you determined your answer. Use words, symbols,
or both in your explanation.
- Mr. Blake, a bus driver for the city bus company, reported that 44 passengers
who rode on his bus one morning paid using a token. Based on this survey,
estimate how many passengers rode on his bus that morning. Use mathematics
to explain how you determined your answer. Use words, symbols, or both in
your explanation.
- Should a different city use these survey results to predict the number of bus
passengers that would be expected to use exact change to ride the bus in their
city? Use mathematics to justify your answer.
