Answer:
Let g = number of hairs Mr. Gelsomino lost
Let c = number of hairs Mr. Chiarilli lost
Part (a)
If Mr. Chiarilli has lost 240 more hairs than Mr. Gelsomino lost, then the number of hairs Mr. Chiarilli has lost is:
240 + g
Part (b)
If Mr. Chiarilli has lost 240 more hairs than Mr. Gelsomino lost, then Mr. Gelsomino has lost:
c - 240
Part (c)
If Mr. Gelsomino has lost 60 hairs then:
⇒ 60 = c - 240
⇒ c = 60 + 240
⇒ c = 300
Therefore, Mr. Chiarilli has lost 300 hairs
