Monday: x watermelons

Tuesday: 2x watermelons

Wednesday: 1/2x

Thursday: 18

Friday: 4+2(x+2x)=2(3x)=6x+4

x+2x+1/2x+18+6x+4=60, 9 1/2x=38, 19/2x=38, x=38*2/19, x=2*2=4.

So, 6(4)+4=24+4=28 watermelons.

Monday: x watermelons

Tuesday: 2x watermelons

Wednesday: 1/2x

Thursday: 18

Friday: 4+2(x+2x)=2(3x)=6x+4

x+2x+1/2x+18+6x+4=60, 9 1/2x=38, 19/2x=38, x=38*2/19, x=2*2=4.

So, 6(4)+4=24+4=28 watermelons.

Pungce, why did you not respond to my question I asked on your last post?

I thought that was very rude.

 

You did not give Dimitristhym any feedback either. That was also rude. If you did not understand his answer, or it was too complicated or badly presented to follow, or if you thought it was wrong then you should have said so. You should not just ignore people!
