.1d + .25q = 2.00  solve for q this lets us state quarters in terms of dimes.

.25q = 2 - .1d

q = (2 - .1d)/.25

q = 8 - .4d

d | 0 | 5 | 10 |              Dimes have to be in multiples of 5 because we cannot use nickels.

----------------------------------------

q | 8 | 6 |  4  |              Quarters are in multiples of 2 sue to the dimes.

label the y - axis as q, in multiples of 2, and the x axis as d, in multiples of 5, and now you can graph.
