Answer:
-9=b
Step-by-step explanation:
1. combine multiple turns into a single fraction.
2. multiple all terms by the same value to eliminate
fraction denominators.
3. simplify
4. divide both sides of the equation by the same term
5. simplify
Percentage of increase = 300%
Initial amount = $25
So amount of increase = (300/100) * 25
= 3 * 25
= 75 dollars
Then the final amount = (25 + 75) dollars
= 100 dollars

Answer:
b = 33.546.
Step-by-step explanation:
a + b + c = 77 (1)
a - 5 = b + 5 (2)
a = 5c (3)
from equation 2:
a - b = 10
Adding this equation to equation 1:
2a + c = 87
But a = 5c so
10c + c = 87
c = 87/11 = 7.909
and a = 5*7.909 = 35.545.
b = 77 - 7.909 - 35.545
= 33.546
