Answer:

  • $6.5*1.1*1.3 = $9.30

Given

  • Initial price = $6.5
  • First increase = 10%
  • Second increase = 30%

Solution

Price after first increase:

  • 6.5 + 10% =
  • 6.5 + 6.5*10/100 =
  • 6.5*(1 + 0.1) =
  • 6.5*1.1 =
  • 7.15

Price after second increase:

  • 7.15 + 30% =
  • 7.15 + 7.15*30/100 =
  • 7.15(1 + 0.3) =
  • 7.15*1.03 =
  • 9.30 (rounded to the nearest cent)

The two steps above can be combined as:

  • $6.5*1.1*1.3 =
  • $9.30
