A sugar donut has 110 more calories than twice the number of calories in a slice of brown bread.
A. If x represents the number of calories in a slice of brown cread, write an expression that represents the number of calories in a sugar donut.
B. Write an expression that represents their number of calories together.
C. Write an inequality that represents that together they contain at least 194 calories.
D. What is the smallest number of calories in the slice of bread?

You can put this solution on YOUR website! A sugar donut has 110 more calories than twice the number of calories in a slice of brown bread.
A. If x represents the number of calories in a slice of brown bread, write an expression that represents the number of calories in a sugar donut.
Let "y" be number of calories in a sugar donut.
-------------------
x = calories in brown bread
y = calories in sugar donut
y = 2x + 110
--------------------
B. Write an expression that represents their number of calories together.
x + y = x + 2x+110 = 3x + 110
------------------------------------
C. Write an inequality that represents that together they contain at least 194 calories.
3x + 110 >= 194
--------------------
D. What is the smallest number of calories in the slice of bread?
x <= (y-110)/2
y must be >= 110
If y = 110, x = 0
========================
