A video merchant sold 24 cases of tapes, which was 20% of what he had left. What percent of tapes did he sell?

Naddika [18.5K]

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:

$20\%\rimes x = 24\\\\\dfrac{20}{100}\times x = 24\\\\x = 24\times 5 = 120$

Thus, total number of tapes =

$=24 + 120 = 144$

Percentage of tapes sold =

$=\dfrac{24}{144}\times 100\% = 16.67\%$

Thus, 16.67% of cases of tapes were sold.

What is the solution of log(2t+4) = log(14-3t)?

Serhud [2]

log(2t+4)=log(14-3t)

[Divide both sides with log, since both sides have log, division removes the log]

2t+4=14-3t

2t+3t=14-4

5t=10

t=2
