A. The amount of money she must earn in the summer must be
x ≥ 2450
B. The inequality that describes the situation is
30x ≤ 2000
C. Solving the inequality
x ≤ 66.67 ~ 66 weeks
D. The answer is Part C means that she can only make use of the $2000 money for food for 66 weeks before it's not enough.
I assume the question asks to expand the expression to individual terms.

=x(y+1)+(y+2)(y+1)
=xy+x+y^2+3y+2
