Christopher needs to create so that his time spent will be the same as his current time, the equation could be: 2.4x = 1.2x + 15
Im not an expert or anything, but i think for the innequality, i would say

as far as the amount of people she can invite, do 500-100=400 because of the setup fee, then, to find how many people she can invite. 400÷6.50 which leaves you with the highest amount of people she can invite without going over budget, as 61.
I think Point A and B are 2 inches apart or all of them is right
<h2>1.</h2>
z + 38° = 180°
(L.P)
z = 142°
y = 32° (alternative angle of angle FCA)
x = 142° (alternative angle of angle z)
<h2>2.</h2>
x + 65 = 180
(l.p)
x = 180 - 65
x = 115°
y = x (alternative angle of x)
y = 115°
z = y (V.O.A)
z = 115°
