There is a total of 20 quarters stacked in four piles. The first pile has 3 fewer than the second pile. The second pile has 2 more than the third pile. The fourth pile has 1 more than the second pile. How many quarters are in the fourth pile?

#1**+1 **

p1 = p2 -3

p2

p3 = p2 -2

p4 = p2+1 summed = 20

p2 - 3 + p2 + p2-2 + p2 + 1 = 20

4 p_{2} -4 = 20

p_{2} = 6 ** then p _{4} = 7 **
