Answer:
5.25 hours
Step-by-step explanation:
The calculation of the time needed to schedule for all seven applications is shown below:
Since 3 by 4 is required of an hour to meet you show them
i.e.
= 3 ÷ 4 of an hour
= 3 ÷ 4 × 60 minutes
= 45 minutes
Now for seven applications, the time would be
= 7 × 45 minutes
= 315 minutes
And, one hour = 60 min.
So, the time required is
= 315 minutes ÷60 minutes
= 5.25 hours
Answer:
$3 for 1 book.
Step-by-step explanation:
Cameron's current service charge of $0.95 per song, and the new service charge of $0.89 per song and $12 fee for joining, gives;
- Formula for finding the number of songs that makes the cost of both services the same is; 0.95•s = 12 + 0.89•s
- Computing the value of <em>s </em>that satisfies the above equation gives the number of songs at which the cost of both service is the same as 200 songs
- The interpretation is the the cost of either service is the same when 200 songs are downloaded
<h3>How can the equation that gives the required number of songs be found?</h3>
To Formulate
The charges for songs on the current music service is, C1 = 0.95•s
The charges for the new download service is, C2 = 12 + 0.89•s
Where the $12 is the joining fee
When the cost is the same for both service, we have;
C1 = C2
Which gives;
The equation to represent when the cost for both service is the same is therefore;
0.95•s = 12 + 0.89•s
Computing;
The number of songs that gives the same costs is therefore;
0.95•s = 12 + 0.89•s
12 = 0.95•s - 0.89•s = 0.06•s
s = 12 ÷ 0.06 = 200
- The number of songs at which the cost of each option will be the same is <em>s </em>= 200 songs
Interpreting the solution;
The interpretation is, the cost of songs downloaded on both service will be the same, when 200 songs are downloaded.
