A magician has 3 more red hats than black hats and 4 fewer purple hats than black hats and has 14 hatsin all. How many hats of each color does he have. Show how you got the answer.

  • math -

    You can get the answer by using algebra or by guessing the number of black and seeing what works.

    Perhaps you are not learning algebra yet.

    If I guess there are 5 black hats, then there are 8 red ones and 1 purple one. The sum is 14. So that's the answer.

  • math -

    B+3=R

    B-4=P

    B+P+R=14

    substitute for P and R

    (B)+(B-4)+(B+3)=14

    3B-1=14

    solve from here
