Making Each Balloon Different

Here is the (slightly defective) program:

' Draw 10 Red Balloons
SCREEN 12     ' start up graphics
COLOR 4       ' set the pen color to red
'
LET BALLOON = 1              ' start with balloon number 1
DO WHILE BALLOON <= 10       ' end with balloon number 10
  CIRCLE (100, 100), 25      ' draw a balloon
  LET BALLOON = BALLOON + 1  ' go on to next balloon
LOOP

END

This program will run. It will even draw a picture. But the picture will be a single red circle with radius 25, centered at X=100, Y=100. Boring...

We need 10 balloons, each with a different center, as in the above picture. You might want the first center to be (X=64, Y=100), the next center to be (X=128, Y=100), the center after that to be (X=192, Y=100), ... and so on.
