Prices changed from 100% price to 80% price due to sale.
100% - 20% = 80%
THEN increased by 25% so
80% + 25% = 105%
so the overall effect is that the price rose from the original (100%) to 105%
so a 5% increase
Answer:
Answer: 0.141 kilos
0.141748
Step-by-step explanation:
The quadratic formula is

A = 2
B = -30
C = 108
plug in the values for the equation and you'll get what the factors are
-(-30)+√(-30)²-4(2)(108))/2(2)
and
-(-30)-√(-30)²-4(2)(108))/2(2)
This will give you your A values
and just round the answers from both of the above equations
The answer is3000.Hope it helps
