Original price = $30
Increase in 50% = 50% of $30 = 0.5 x 30 = $15
Price = 30 + 15 = $45
50% off
50% of $45 = 0.5 x 45 = $22.50
Price = 45 - 22.50 = $22.50
No, the sales price is not $30

Answer:
Step-by-step explanation:
Given that
-3a+6b=a+4b
We want to make b subject of formula
First to remove the 4b in the Right hand side of the equation
Subtract 4b from both side of the equation
-3a+6b-4b=a+4b-4b
Then we have,
-3a+2b=a
Now to remove the -3a from the left hand side of the equation add 3a to both side
Then,
-3a+2b+3a=a+3a
2b-3a+3a=4a
Then, 2b=4a
Divide both side by 2
2b/2=4a/2
b=2a.
