There are 420 students in kindergarten through third grade if 1/4 of the students are in first grade 20% are in the second grade
and 115 students are in the third grade how many students are in kindergarten explain
2 answers:
Let x be kindergarten students
x = 420 - [(0.25*420) + (0.2*420)+115]
x= 420 - (105 + 84 + 115)
x= 420 - 304
x= 116 kindergarten students
