c) 3n+2 d)3n+2n

Answer 1

Step-by-step explanation:

560$=separated in ratio 2:3:9

So let take 2x:3x:9x

Add all 14x =560$

X =560/14 =40

2x=2*40=80

3x=3*40=120

9x=9*40=360

360-80 = 280

280 is the difference between the largest share and smallest share.

60% of a number is 90

So

60/100*x=90

60*x=90*100

X=9000/60=150 so the number is 150
