The rates for Internet use offered by three companies are shown below.
Company A: $6.00 every 90 minutes of use
Company B: $2.75 every 45 minutes of use
Company C: $3.00 for every 60 minutes of use
Which company offers the lowest rate per minute?
What do you think you should do with these pairs of numbers? Add? Subtract? Multiply? Divide?
I'm pretty sure that you could either multiply or divide.
Which one will give you reasonable answers?
For B, I'd multiply it by 2 to get 90, then mutliply $2.75 by 2 to get 5.50.
Multiplication works better for me.
But then again, it's asking for the lowest rate per MINUTE.
Do you mean that you'd pay $5.50 per minute??
The company only charges $2.75 for 45 minutes!!
Ohh.
Well, know I to divide instead.
Can I take $5.50 and divide it by 90 to get my answer for B?
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?
