You are in charge of the staff party. Your boss gives you a budget of $1000 to get everyone plaid pajamas which cost $72 or reindeer slippers which cost $10 .
You must buy 69 gifts. How many of each will use up every dollar?
72p + 10s = 1000
ps = 69
72p + 10s = 1000
p + s = 69
72p + 10s = 69
ps = 1000
72p + 10s = 69
p + s = 1000
