Answer:
See answers below
Step-by-step explanation:
Given the function:
f(x) = 0.15x + 900
a) f(80) = 0.15(80) + 900
f(80) = 12 + 900
f(80) = 912
b) f(120) = 0.15(120) + 900
f(120) = 18 + 900
f(120) = 918
c) f(200) = 0.15(200) + 900
f(200) = 30 + 900
f(200) = 930
d) f(56) = 0.15(56) + 900
f(56) = 8.4 + 900
f(56) = 908.4
A net can be used to find the area of a specific side or the entire surface area. It can also help to find the perimeter. To find the surface area with a net, solve for the area of each shape in the net and add them together to get the total area (surface area).
Hope this helps!

Answer:
Last part 24x
Step-by-step explanation:
I understand some of this, like the last question. if each class had 24 pupil, and were trying to find out how many are in each class, it would be 24x (x stands for the amount of classes)
You have not given a true amount of pupils so I can not give a 100% correct answer for the first part.
