Ms. Garcia's homeroom because 28•3=84 and that means that since it said that her class sold 98 magazine subscriptions, it means that some students sold more.
And in Mr.Brown's class 24•3=72 so each student in his class only sold 3 magazine subscriptions each and no one sold more.
So, the answer is Ms. Garcia's Homeroom.

Tu examen es para potos
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
radical 8 = radical 4 * radical 2 = 2*radical 2
H(t) = Ho +Vot - gt^2/2
Vo = 19.6 m/s
Ho = 58.8 m
g = 9.8 m/s^2
H(t) = 58.8 + 19.6t -9.8t^2/2 = 58.8 + 19.6t - 4.9t^2
Maximun height is at the vertex of the parabole
To find the vertex, first find the roots.
58.8 + 19.6t - 4.9t^2 = 0
Divide by 4.9
12 + 4t - t^2 = 0
Change sign and reorder
t^2 - 4t -12 = 0
Factor
(t - 6)(t + 2) =0 ==> t = 6 and t = -2.
The vertex is in the mid point between both roots
Find H(t) for: t = [6 - 2]/2 =4/2 = 2
Find H(t) for t = 2
H(6) = 58.8 + 19.6(2) - 4.9(2)^2 = 78.4
Answer: the maximum height is 78.4 m
