Hey there,
2 hours = 15 pages
1 hour = 15 / 2
= 7.5 pages
15 pages = $40
1 page = $40 / 15
= $2.666666666666667
7.5 pages= $2.666666666666667 x 7.5
= $20
Hope this helps :))

Remark
If you just want the way this would be written out the answer is
Note
1. The quotient is the answer of a division problem.
2. The number is represented by the letter x
the answer is x equal 100
We will use sine for this. Pls see the below explanation. Hope it helps but I’m not entirely sure as I do not know if you can choose any trigonometry law or must use a specific law. Good luck!
