Answer:
177.3 feet
This is a classic find the vertex of a parabola question.
if this was a calculus class the solution would be to take the derivative and set it equal to zero... -32t+ 105 = 0
BUT i assume that you are not in a calculus class..
so we try plan "B" the highest (or lowest) point of parabola is it's vertex
the vertex formula is [-b/2a,f(-b/2a)]
in your problem a = -16, b=105, c= 5
so the "X" (TIME) is located at -(105)/(2*-16) = 3.28
plug in 3.28 into -16(3.28)^2 + 105(3.28) + 5 = 177.27
and you will get

y = Bracelets
x = Necklaces
Half Hour for the Necklaces; One Hour for the Bracelets; Fewer than Twenty-Hours.
Answer: 0.5x + y < 20
At Least Twice as many Bracelets, as Necklaces.
Answer: y ≥ 2x; x > 0
Answers:
Letter Choices;
(B) 0.5x + y < 20,
(C) y ≥ 2x,
(F) x > 0
Hope that helps!!!!! : )
Answer: choice A
Step-by-step explanation:
f(x) = log2 x
f(40) = log2 40
40 = 2^y
2^5 = 32 and 2^6 = 64
so f(40) lies between integers 5 and 6.
