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.
