Question 167273
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
