Math Problem Statement

cd city sells 5 CDs for $49 music land sells 8cds for 59.50 which store is the better place to buy cds

Solution

To determine which store offers the better deal, we need to calculate the cost per CD at each store.

1. CD City:

  • Price for 5 CDs = $49
  • Cost per CD = 495=9.80\frac{49}{5} = 9.80

2. Music Land:

  • Price for 8 CDs = $59.50
  • Cost per CD = 59.508=7.44\frac{59.50}{8} = 7.44

Conclusion:

  • CD City charges $9.80 per CD.
  • Music Land charges $7.44 per CD.

So, Music Land is the better place to buy CDs because the cost per CD is lower.
