Answer:
y is equal to 9,600 and z is equal to 40,000
Explanation:
In order to find this, you need to divide the number for x by the percentage of y that it makes up. This will give us the y value.
y = 480/5%
y = 480/.05
y = 9,600
Now we just complete the same operation dividing y by its percentage to find z.
z = 9,600/24%
z = 9,600/.24
z = 40,000
