Question

A stackable CD rack holds 25 CDs and costs $4. Charlie has a collection of 150 CDs. How much will it cost him to buy enough racks to hold all of his CDs?

Answer 1

25 cds for $4

So he has 150 cds and needs to store all of them. Therefore you would divide one rack which can hold ( 25 cds) by the amount of cds you own.

150 divided by 25 is 6
That means you will need 6 racks to hold all 150 of the cds.
Now you need to calculate the cost. To calculate the cost you have to multiply the amount of racks you need by the cost. so,

6x$4 the amount then equals to $24.

the answer: It will cost Charlie a total amount of $24 dollars to buy 6 racks to hold all 150 of his cds.

Answer 2

It will cost him a total of $24.

Explanation:

Each Rack Holds 25 CDS so 150 CDS would need 6 racks.

Then after this you would need to multiply 6 by 4 because 4 is the cost per rack.

So 6 times 4 would give you the answer $24
