Quick, need answers for 21, 22, and 23, with a step by step explanation.

21) $90    22) $144     23) $240.5

22) CTS: 90    M:60

     Turn 60% into 0.60

     Multiply the CTS, 90, to 0.60 to get 54

     Add 54 and 90 together to get 144

23) CTS: 130    M:85

      Turn 85 into 0.85

      Multiply the CTS, 130, to 0.85 to get 110.5
