Answer(s):

  • x + 0.2x
  • 1.2x

Solution:

We know that:

  • Brookie = x dollars
  • Benji = x + (20% × x)

Solution:

To see which expression has been used, we will need to simplify the expression.

  • Benji = x + (20% × x)
  • => Benji = x + (20/100 × x)
  • => Benji = x + (2/10 × x)
  • => Benji = x + (0.2 × x)
  • => Benji = x + (0.2x)
  • => Benji = x + 0.2x
  • => Benji = 1.2x

Option A and B are correct.
