Question 1099612
frank, sam, and louis went to lunch. sam's meal cost $.45 less than frank's. louis's meal cost twice as much as sam's. if the bill came $9.25, how much does each person owe? 
----
Equations:
s = f-.45
L = 2s
s + L + f = 9.25
---------------------
Substitute for f and for L and solve for "s"::
s + 2s + s+0.45 = 9.25
-------------------
4s + 0.45 = 9.25
4s = 8.8
s = $2.20
L = 2s = $4.40
f = s + 0.45 = $2.65
