The number of books Alisha did not sell after making a profit of £490 is 45 books
<h3 />
How to find how many book she sell base on the profit?
She buys 200 books costing £3 each.
Therefore,
cost = 3 × 200 = £600
Hence,
She sells 2/5 of the books at £8 each.
total amount = 2 / 5 of 200 × 8
total amount = 80 × 8
total amount = £640
Alisha then reduces the price of the remaining books by a quarter.
She then sells some of the remaining books.
Therefore,
the remaining book = 120
She sold some of the remaining books.
profit = selling price - cost price
490 = selling price - 600
selling price = 490 + 600
selling price = £1090
Therefore,
the cost of the remaining book she sold = 1090 - 640 = £450
Hence,
let
x = number of book sold
6(x) = 450
x = 450 / 6
x = 75
The number book she did not sell = 120 - 75 = 45

Your domain for the graph would be (negative infinity, 0] or {x|x less than or equal to 0} and your range would be [0, infinity) or {y|y greater than or equal to 0}
That being said, your answer would be B. The domain is all realy numbers that are less than or equal to 0.
