Question 381522
Six sandwiches and five sodas cost $36.95. Five sandwiches and five sodas cost $32.20. What is the cost of one sandwich and the cost of one soda?
----
Equations:
6d + 5s = 3695 cents
4d + 5s = 3230 cents
-----------------------
Subtract and solve for "d":
2d = 465 cents
d = 232.5 cents
----
A sandwich costs $2.33 
----
Substitute and solve for "s":
4(232.5) + 5s = 3230
930 + 5s = 3230
5s = 2300
s = $4.60 (Price of a soda)
