Homework for periods 2,4: Finish the graphing guy.  It should look like a guy with his striped tie blowing away.

Period 1,3,5,7: Finish 1-6 on the word problems.  If you need some help setting up the equations, look below to see the basic equations used to set up 4-6.

#4
d = dollar bills
f = five dollar bills

d + 5f = 124
d + 8 = f



#5
n = number of nickels
q = number of quarters

5n + 25q = 260
n + q = 16


#6
T = twenty cent stamps
F = twenty five cent stamps

T + F = 32
20T + 25F = 740
