Answer 2

We will use division operator to solve this word problem. Division operator is used when the problem asks for 'one,' 'each,' or 'per'.

Total amount to buy CDs for friends party = $90

Cost of each CD = $18

The possible numbers of CDs that can be bought is calculated by dividing $90 by $18.

=
`\$ 90 / \$18`

=
`(90)/(18)`

= 5 CDs
