Answer:

4b+8 = 20

---------------

4b = 20

-------------------

b = 5

Step-by-step explanation:

We need to solve for b in the following equation:

$\frac{4b + 8}{2} = 10$

When we multiply each term by 2 the denominator cancels out:

$\displaystyle 2 \times \frac{4b + 8}{2} = 10 \times 2\\\\4b + 8 = 20$

Next, we subtract 8:

$4b +8 - 8 = 20 - 8\\4b = 20$

Final step, we isolate the variable. We cancel the multiplication on the left side when dividing by 4 on each term

$\displaystyle 4b = 20\\\\\frac{4b}{4} = \frac{20}{4}\\\\b = 5$

What is percentage change?

By quantifying the difference between two numbers and expressing it as an increase or decrease, the Percentage Change Calculator (percent change calculator) may determine the percentage change.

The initial price $V_{1}$ (100%) was decreased by 10%., then this reduced price is reduced more by 20% that becomes the final price $V_{2}$ which is 72.
