SOLUTION: if you have 575 apples, and have eaten 228, how many apples do you have to add, and eat, to make it 50% eaten? (not just 1/2 of 575). I think you start it as: 228 +x / 575 +x =

Question 1037361: if you have 575 apples, and have eaten 228, how many apples do you have to add, and eat, to make it 50% eaten? (not just 1/2 of 575). I think you start it as:
228 +x / 575 +x = 50%. Solve for x. But, I might be wrong.

You can put this solution on YOUR website!
In words, you eat some apples, then you add more apples, you
eat those and you end up with 50% of all the apples eaten.
-----------------------------
+575+-+228+=+347+ apples not eaten
Add +x+ apples
Now the total ( eaten + not eaten ) = +575+%2B+x+
You eat the +x+ apples
The total eaten apples is now +228+%2B+x+
------------------------------------
+%28+228+%2B+x+%29+%2F+%28+575+%2B+x+%29+=+.5+
+228+%2B+x+=+.5%2A%28+575+%2B+x+%29+
+228+%2B+x+=+287.5+%2B+.5x+
+.5x+=+59.5+
+x+=+119+
---------------
119 apples should be added, then eaten
---------------
check:
+%28+228+%2B+x+%29+%2F+%28+575+%2B+x+%29+=+.5+
+%28+228+%2B+119+%29+%2F+%28+575+%2B+119+%29+=+.5+
+347+%2F+694+=+.5+
+.5+=+.5+
OK
I agree with you
