Answer:
c = 40 g
Step-by-step explanation:
Let's call the tennis balls and the cube
The three balls weigh the same.
Both cubes weigh the same
We know that two balls and a cube weigh 152g.
This is:
2p + c = 152 (i)
A ball and a bucket weigh 96 g.
This is:
p + c = 96 (ii)
Then substitute (ii) in (i)
2p + (96-p) = 152
p +96 = 152
p = 56 (iii)
Now substitute (iii) in (ii)
c = 96 -56
Finally
c = 40 g
