Factor out P:
p(-3n+5)=½
Divide both sides by -3n+5:
p(-3n+5)^-3n+5
½^-3n+5
p=1^-6n+10
So five pages of her fiction book in 7 minutes. And she must read thirty pages:
30/5 = 6.
6 * 7 = 42 minutes for the fiction book.
So 2 pages of her history book in seven minutes.
30/2 = 15.
15 * 7 = 105 minutes for the history textbook
Add:
42 + 105 = 147 minutes.
