Question

Sam read 30 of the assigned book already and reads 34 pages per night. Charlie read 100 already and reads 20 pages per night. How many nights will it take for Sam to be ahead of Charlie in the book?

Answer 1

Sam: y = 30 + 34x
Charlie: y = 100 + 20x
30 + 34x = 100 + 20x
14x = 70, x = 5(equal)
It will take 6 nights for him
