Suppose you have just enough money, in coins, to pay for a loaf of bread priced at $1.95. You have 12 coins, all quarters and dimes. Let q equal the number of quarters and d equal the number of dimes. Which system models the given information?
A. q + d = 12 B. 25q + 10d = 195
q + d = 1.95 q + 12 = d
C. 10q + 25d = 12 D. q + d =12
q + d = 1.95 25q + 10d = 195
