Answer:
The interest charged is $7.49.
After 29 days, Travis paid a total of $607.49
Step-by-step explanation:
Travis obtained a cash advance for $600.
The interest rate is 0.04305% per day.
The simple interest rate formula is given by:
Where <em>I</em> is the interest, <em>P</em> is the initial amount, <em>r</em> is the rate, and <em>t</em> is the time (in this case in days).
Our initial amount <em>P</em> is $600.
Our interest rate <em>r</em> is 0.04305% or (moving the decimal two places to the left) 0.0004305.
Since Travis repaid the loan after 29 days, our <em>t</em> is 29.
Hence, our interest is:
So, the interest charged is about $7.49.
So, after 29 days, Travis paid a total of the original $600 plus an interest of $7.49 for a total of $607.49
Answer:
is the required probability.
Step-by-step explanation:
Total number of Marbles = Blue + Red
Probability of getting blue
Probability of not getting a blue
To get exactly one blue in two draws, we either get a blue, not blue, or a not blue, blue.
<u>First Draw Blue, Second Draw Not Blue:</u>
1st Draw:
2nd Draw: (since we did not replace the first marble)
To get the probability of the event, since each draw is independent, we multiply both probabilities.
<u>First Draw Not Blue, Second Draw Not Blue:</u>
1st Draw:
2nd Draw: (since we did not replace the first marble)
To get the probability of the event, since each draw is independent, we multiply both probabilities.
To get the probability of exactly one blue, we add both of the events:
