We have a question: Coral reads 30 pages of a book on night 1, and 2 less than twice that on night 2. Night 3 Coral reads 3 more pages than the sum of the first two nights. How many total pages did Coral read in the 3 nights?
And an answer: 179
So how you got the answer?
Night 1:30 pages. Night 2:2(30) - 2 = 58 pages. Night 3:3 + (30 + 58) = 91 pages. Total:30 + 58 + 91 = 179 pages.
