B)
1.80c +3h = 288.60
c=1 -2h
1) Gathering the data
Cold lunch (c) : $1.80
Hot lunch (h) : $3.00
Total $288.60
c = 1 -2h
2) Let's set up a system of equations, based on that
1.80c +3h = 288.60 <em>This equation relates the cost of those lunches</em>
c=1 -2h <em>The relationship between the number of lunches</em>

Answer: x = 7
Step-by-step explanation:
Corresponding angles have congruent measures. Thus, 11x - 2 = 75
11x - 2 = 75
11x = 77
x = 7
