The sum of the costs in parts a and c is less than $120. Write and solve an inequality to determine the possiblities for the number of compact disks Merle purchased.

10.5x + 8(x+3)< 120

I know the answer is x< 5.189

Here is how I did it but I believe it is wrong.

10.5x + 8(x+3)<120

10.5x + 8x+3<120

18.5x + 3< 120

18.5x + 3-3<120-3

18.5x<117

X<6.324(wrong)

Help please

ere is how I did it but I believe it is wrong.

10.5x + 8(x+3)<120

10.5x + 8x+24<120

Thank you so much.
