Answer:

16.67% of cases of tapes were sold.

Step-by-step explanation:

We are given the following in the question:

Number of cases of tapes sold = 24

Thus is 20% of tapes left.

Let x be the total number of tapes left.

Thus, we can write:

[tex]20\%\rimes x = 24\\\\\dfrac{20}{100}\times x = 24\\\\x = 24\times 5 = 120[/tex]

Thus, total number of tapes =

[tex]=24 + 120 = 144[/tex]

Percentage of tapes sold  =

[tex]=\dfrac{24}{144}\times 100\% = 16.67\%[/tex]

Thus, 16.67% of cases of tapes were sold.
