    What do you think you should do with these pairs of numbers? Add? Subtract? Multiply? Divide?

  • Math -

    I'm pretty sure that you could either multiply or divide.

  • Math -

    Which one will give you reasonable answers?

  • Math -

    For B, I'd multiply it by 2 to get 90, then mutliply $2.75 by 2 to get 5.50.

  • Math -

    Multiplication works better for me.

  • Math -

    But then again, it's asking for the lowest rate per MINUTE.

  • Math -

    Do you mean that you'd pay $5.50 per minute??
    The company only charges $2.75 for 45 minutes!!

  • Math -

    Ohh.

    Well, know I to divide instead.
    Can I take $5.50 and divide it by 90 to get my answer for B?

  • Math -

    So here are my results for all:
    Company A: 0.07 c/minute
    Company b: 0.06 c/minute
    Company C: 0.05 c/minute

    So the answer would be C?

    Yay! You've got it! :-)
