cost of DVDs = 14.99
no. of DVDs = x
should not exceed = 65.75

14.99x < 65.75    

++++
14.99x < 65.75
÷14.99    ÷14.99
        x < 4.38        *Stefan should buy 4.38 DVDs or less.

Assuming Stefan bought 4 DVDs
14.99x     < 65.75
14.99(4)  < 65.75
59.96       < 65.75   * inequality is correct

Assuming Stefan bought 5 DVDs
14.99x    < 65.75
14.99(5) < 65.75
74.95      < 65.75  
*if Stefan buys 5 DVDs then, the inequality will become false.
