Step-by-step explanation: Here's the explanation if you're confused:
You first need to find the volume of Pyramid A with the Volume formula of a square pyramid which is: V=a² where a is the base edge, and h is the height.
Plugging in what we know: V = 8² x 9/3 = 192 in³.
From here, we need to compare the two volumes by dividing.
2,880 in³ ÷ 192 in³ = 15.
So, pyramid B's volume is 15 times bigger than the volume of Pyramid A.
The children's ticket is $6 and an adults ticket is $8.
Set up two equations, 2A+C=22 and A+3C=26. Rearrange the second equation to A=26-3C. Now plug this in to the first equation so you get 2(26-3C)+C=22 and solve
