Buzz is three times as heavy as Jessie. If Buzz is 450g heavier than Jessie what is the weight of Buzz in grams?

Answer 1

B = 3 J ... J = B/3

B = J + 450
... B = B/3 + 450
... 2B/3 = 450
... B = 450 * 3/2

Answer 2

675g

Answer 3

B = 3J - 450g
J = 225g
225 x 3 = 675g
675g - 450g = 225g (Jessies weight)

Therefore Buzz must weigh 675g
