• For a day, her gross earnings are of $72.

• For a week, her gross earnings are of 72 x 7 = $504.

Proportions:

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.
