Answer:
The answer to your problem is, 80% of 1080 = 864
Explanation:
First lets find out what is 50% of 1080.
Which is:
1080 / 2
= 540.
Next we should find out what is 30% of 1080.
Because remember 30% + 50% = 80%
Now 30% of 1080 which is:
324.
Next add our number which is:
540 + 324 = 864.
864 = 80% of 1080
Thus the answer to your problem is, 80% of 1080 = 864
