5. A study conducted at a school showed that the batteries used by calculators
lasted an average of 110 days with a margin of error of +10 %.
a. What is the minimum average number of days a teacher can expect to have
the batteries last in her classroom?
b. There are roughly 299 days from the first day of school until the last day of
school. The teacher has 24 TI-84 calculators and each one requires 4 triple A
batteries. If the teacher can buy triple A batteries wholesale at 55 cents a battery,
how much do you think she will need to spend at most on batteries for calculators
over the year?
