Answer:
Part A: B
Part B: 1
Step-by-step explanation:
<u>Part A</u>:
The meaning of "at most" is "less than or equal to." If we assume that the variables x and y represent numbers of loaves of banana bread and nut bread, respectively, then the first problem statement tells you ...
x + y ≤ 30 . . . . . the total of loaves baked is at most 30
Only one answer choice has this inequality listed: choice B.
__
<u>Part B</u>:
The numbers of loaves of bread will not be negative. The only quadrant that has both coordinates positive is the 1st quadrant.

<em>Comment on quadrant</em>
Real-world problems involving numbers of items are often expressed in terms similar to those seen here. The assumption that is made in all such problems is that the quantity of items cannot be negative. That is, the constraints x ≥ 0 and y ≥ 0 are always considered part of the problem description. These limit solutions to Quadrant 1. (or I, if you use Roman numerals for numbering quadrants)
