There are 4 fifith grade classes in school. each class has 24 students. for each gym period, two fifth grade classes take gym together. there are 10 periods in all during a week. what information is not needed to figure out how many total students take a gym period together?

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )

step-by-step explanation:

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
