Suppose you have just enough money in coins to pay for a small bag of carrots priced at $1.95. You have 12 coins, all quarters and dimes. Let q = the number of quarters and d = the number of dimes. Which system below best models this problem? You must think outside the box to get this one! You don't need to solve it, just set it up. Aq+d = 12 : q+d = $1.95 B. 10g + 25d = 12 : q+d = $1.95 C. 25q + 10d = 195 q+ 12 = d D. q +d = 12 : 25q +.10d = 1.95

A. q +d = 12:
q +d = $1.95
B. 10q + 25d = 12:
q+d = $1.95
C. 25q + 10d = 195:
q+ 12 = d
D. q +d = 12
25q+ .10d = 1.95
