Linear Inequalities - Carisa Chan
Round up the prices of the DVD and CD.
DVD is $24.99
≈ 25
CD is $11.99
≈ 12
We take the total amount of money we have to minus off the cost of the DVD first.
$100 - $25 = $75
Then, take $75 divide by $12.
$75 / $12 = 6 R 3
Therefore, the most number of CDs I can buy is 6.
