The school owns 2 classroom sets of 30 calculators each, which students are required to have during their mathematics class. There are 2 calculators from one set and 6 calculators from the other set that are not available for use by the students because these calculators are being repaired. For which of the following class periods, if any, are there NOT enough calculators available for each student to use a school-owned calculator without having to share?

Answers

None since only 8 are being fixed and they have two sets of calculaters which is a grand total of 60 with the 8 calculators. Once the the 8 are are subtracted from the equation there would be 52 and there is less students in the classroom for each class leaving extra calculators to be used.
There's not enough information here.
