# 1993 AJHSME Problems/Problem 10

## Problem

This line graph represents the price of a trading card during the first $6$ months of $1993$. $[asy] unitsize(18); for (int a = 0; a <= 6; ++a) { draw((4*a,0)--(4*a,10)); } for (int a = 0; a <= 5; ++a) { draw((0,2*a)--(24,2*a)); } draw((0,5)--(4,4)--(8,8)--(12,3)--(16,9)--(20,6)--(24,2),linewidth(1.5)); label("Jan",(2,0),S); label("Feb",(6,0),S); label("Mar",(10,0),S); label("Apr",(14,0),S); label("May",(18,0),S); label("Jun",(22,0),S); label("\textbf{1993 PRICES FOR A TRADING CARD}",(12,10),N); label("\begin{tabular}{c}\textbf{P} \\ \textbf{R} \\ \textbf{I} \\ \textbf{C} \\ \textbf{E} \end{tabular}",(-2,5),W); label("1",(0,2),W); label("2",(0,4),W); label("3",(0,6),W); label("4",(0,8),W); label("5",(0,10),W); [/asy]$

The greatest monthly drop in price occurred during $\text{(A)}\ \text{January} \qquad \text{(B)}\ \text{March} \qquad \text{(C)}\ \text{April} \qquad \text{(D)}\ \text{May} \qquad \text{(E)}\ \text{June}$

## Solution

The graph shows the following price changes:

Jan : Change:-0.50

Feb : Change:+2.00

Mar : Change:-2.50

Apr : Change:+3.00

May : Change:-0.50

Jun : Change:-2.00

Therefore, $\boxed{\text{(B)}\ \text{March}}$ has the largest price drop.
