Question

Julia works at a music store. One of her jobs is to stock new CDs on the shelf. A recent order arrived with 215 classical CDs, 125 jazz CDs, and 330 soft rock CDs.

Part A
julia needs to place the CDs on the sale racks wth 5 CDs in each group. Write two different equations that can be used to show how many groups, g Julia will use to arrange all the CDS.
Equation:

Answer 1

Equation: {[(215+125)+330)]/5} /is divided by.

Answer 2

Total Number of CD's=215 classical CD's + 125 jazz CD's, and 330 soft rock CD's

=215+125+330

=340+330

=670 CD's

Number of CD's that Julia want to place in each group = 5 CD's

There are two ways in which 5 CD's can be placed in a group, either 5 CD's in a row or 5 CD's in a Column.

Let number of rows that contain 5 CD's in a group in the shelf = x

And, Number of Columns which contain 5 CD's in a group in the shelf= y

Equation containing number of groups containing 5 CD's can be written as

→5 x=670

OR

→5 y= 670

Total number of groups in either case will be

`=(670)/(5)\\\\=154`
