Question 564060
a small dinner roll has 10 fewer calories than twice the number of calories in a slice of white bread. Together they contain at least 185 calories. Find the smallest possible number of calories in the slice of white bread. 
----
Equations:
d = 2b-10
d + b >= 185
----------------
2b-10 + b >= 185
3b >= 195
bread >= 63 calories
