Hey Dear,
◆ Answer -
- For N pages manuscript, Net return = 1.5 N - 20
- For 112 pages manuscript, Net return = 148 pesos
● Explaination -
Let N be number of pages in given manuscript.
Investment by Tillie is calculated by -
Total investment = manuscript setup + supplies per page
Total investment = 30 + N × 0.5
Total investment = 30 + 0.5 N
Payment received by Tillie is calculated by -
Total payment = service charge + payment per page
Total payment = 10 + N × 2
Total payment = 10 + 2 N
Net return to Tillie for manuscript of N number pages -
Net return = payment - investment
Net return = 10 + 2 N - 30 - 0.5 N
Net return = 1.5 N - 20
For 112 pages manuscript,
Net return = 1.5 × 112 - 20
Net return = 168 - 20
Net return = 148 pesos
Therefore, Tillie will get 148 pesos net return for 112 pages manuscript.
