Answer:
1000 times
First, we estimated the Sun's width in terms of the Earth's breadth, then the Star's width in terms of the Earth's breadth, and for comparison, we did simple division, which revealed that the Star KW Sagittarii is 1000 times wider than the Sun.
p - 0.27p = $ 219
0.73p = $ 219
p = $ 219 / 0.73
p = $ 300. i don't know if this is fully right tho
