Question

10 CDs costs $2.30. A package of 50 CDs costs $10.50. Which is the better buy?

Answer 1

Answer:

Step-by-step explanation:

Plan A: 10 CDs costs $2.30, so 1 CD cost $0.23

Plan B: A package of 50 CDs cost $10.5, so 1 CD cost $1.05

0.23 < 1.05

Choose Plan A

Answer 2

To get the answer to this question we would have to calculate how much each DVD costs in each scenario.

To do this we will divide each cost by the total number of CDS:

$\frac{2.30}{10} = .23$

$\frac{10.50}{50} = .21$

For the pack of 10 CDS each CD costs 23 cents. On the contrary, for the pack of 50 CDs each CD costs 21 cents. Therefore to get a better deal, you would want to go with the 50 CDs.

Hope this helps!
