The population of a school is 400 students. next year it is expected to be about 120% of what it is now. choose next year's student population from the answers below. a.320 b.80 c.400 d.480

Given:
this year's population: 400 students
next year's population: 120% of this year's population

this year's population x rate of next year's population = next year's population

400 students * 120% = 480 students  CHOICE D.

There will be 480 students next year.

39.
-3^ - 2(-5)(3)
-3*-3= 9
2*-5*3 = -30
9 - (-30)
subtracting a negative really means add.
9 + 30 = 39
