Sarah and Joe are seeking to join a gym. Sarah saw on television that Great Gym is offering membership at $19.50 per month, plus
a one-time registration fee of $59. Joe plans to join Workout World because Workout World only charges $9.50 per month, plus a one-time registration fee of $149.
Which gym membership is a better deal? Explain why.
So first of all, let us take a time limit- suppose of 12 months. This means, the total needed to pay is: 59+12*19.50= $293. In the second case, the registration fee is $149. So the total needed to pay is; 149+12*9.5= $263. So with this, we know the second deal is better, as it costs less at the same period of time than the first deal.
If you know the radius of a circular track, you can use physics to calculate how fast an object needs to move in order to stay in contact with the track without falling when it reaches the top of the loop.
