Oh i did it like this

3x-6+2x+88+108=360

solved and got 34

then i substituted x for 34 in the A equation

3+34-6 and got 31..

so it would be a=31?

So it would be x+2x+30=90

x=20?

That means it is KE? or both?

So that means if the ball rolls it has kinetic energy?

That means the answer is y=7/8+6?

Are you ok?

Then it would be D right?

lol...

Ok, thank you.

so for b i got $240 for the regular price and for the group special $300...

Is this right?

Thank you! I "get it" now

I know the answers but i don't know how to get it

I think its exactly one but im not sure
