Ok so:
90 + 6x - 7.5x < 30
6x - 7.5x = -1.5
90 - 1.5x < 30
-90 -90
-1.5x < -60
-60/-1.5
x=40
40 < 30

Answer:
the answer is 25
Step-by-step explanation:
you subtract 25 from 100 you get 75 and when you subtract 25 from 75 you get 25
we have the equation
2(x-4)=6x+4
solve for x
Apply distributive property left side
2x-2(4)=6x+4
2x-8=6x+4
Group terms
6x-2x=-8-4
combine like terms
4x=-12
divide by 4 both sides
x=-12/4
<h2>x=-3</h2>
68 - 36 = 32 And if each person bought one box its 32 divided by 3 so your final answer is 10.67
