A very old vending machine accepts only nickels (n) and dimes (d). Candy costs up to $0.50, but sometimes the machine will dispense candy without any coins being inserted into the machine. Which inequality shows all of the ways to obtain a candy bar from the machine?
Also need help with this one...When comparing the graphs of y = x and y > x, what is a difference in the graphs?
Hello, I think it could be \( 0 \le 0.05n + 0.1d \lt 0.5\) where \(n\) and \(d\) are number of nickels and dimes.

The answer of the second question is B. Because graph \(y = x\) look like this|dw:1360179286008:dw| and points that satisfy the equation \( y > x \) are all point that lie above the line \(y = x\) but don't lie on the line.
I mean A is the right answer.
Second question is A?
