- For a day, her gross earnings are of $72.
- For a week, her gross earnings are of 72 x 7 = $504.
<h3>Proportions:</h3>
This question is solved using the proportions given, which are:
- Payment of $1.50 per page of 30 lines.
- Retha keys 6 pages per hour.
Hence, in an 8-hour day, she keys 6 x 8 = 48 pages.
Since she earns $1.50 per page, for a day, her gross earnings are of 48 x 1.5 = $72.
Considering a week has 7 days, for a week, her gross earnings are of 72 x 7 = $504.

Answer:
Let n be the number
100% of a number is 15 is written as: 100% × n = 15
100% = 100 / 100 = 1
Hence
100% × n = n = 15
We now need to find 50% of the number
50% of 15 = (50 / 100) × 15 = 750 / 100 = 7.5
