Answer:
Adult plate = 21 , child plate = 11
Step-by-step explanation:
number of adult plate = a , no of child plate = c
$487 = $19a + $8c (equation 1)
32 = a + c (equation 2)
Multiply equation 2 by 8 gets you:
256 = 8a + 8c (equation 3)
Solve equation 1 and equation 3 simultaneously:
487 = 19a + 8c (equation 1) minus
256 = 8a + 8c (equation 3) :
231 = 11a
a = 231/11
a= 21
Substitute a = 21 into equation 2 :
32 = 21 + c
c = 32 - 21
c = 11
So 21 adult plates and 11 child plates were sold.
C
it appears that there are 7 cubes, so divide the overall volume by the seven cubes, making the volume of each one would 8. Volume is length times with times height so you would find the cube root of eight which is two. This means that each side length is 2 so you would find the area of each side and add them all together. This adds up to equal 120.
Hope this helped!!
