In order to calculate the equivalent discount, consider the principle number is 100,
Then, 100 - 100 * 0.20 = 100 - 20 = 80
Now, 80 - 80 * 0.15 = 80 - 12 = 68

So, Total discount would be: 100 - 68 = 32%

Hope this helps!

Adding or subtracting fractions with different denominators

Bas_tet [7]

Step-by-step explanation: You can't continue on with the problem until the denominators are the same. So you need to find the LCD (Least Common Denominator). For example...

$\frac{1}{2} +\frac{1}{3}$ The LCD is six

$\frac{1*3}{2*3}=\frac{3}{6} =\frac{1}{3}$

$\frac{1}{2}+ \frac{1}{3}= \frac{3}{6} +\frac{2}{6}$

$\frac{3+2}{6}= \frac{5}{6}$

Hope this helps, have a BLESSED and wonderful day! :-)

A pair of sneakers are on sale for 20% off the original price. Tom purchased a pair of sneakers at this discounted price of $80.

LUCKY_DIMON [66]

The answer is 100.
You start by making a formula:
.80(x) = 80,
As we know the discount is 20% off, which makes the price actually 80% of what it originally was. Convert percent to a decimal gets you that .80
Reverse the process — 80/0.80 = 100
