Explaining? Simple!
1. In order to find the answer you simply change 25% to decimal form then multiply by your brushes. Then subtract your value from the original:
25% ⇒ .25 [Note: All percentages are less than one]
[840 x .25] = 210
[840 - 210] = 630.
840 decreased by 25% is 630.
2. For this one, you do the exact same thing as the first one, except you add since it is being increased. So convert 7% to decimal form and then multiply it by your money. The add this value to the original:
7% ⇒ .07 [*Note*: This is 7% not 70%]
[84 x .07] = 5.88
[84 + 5.88] = $89.88. (Don't forget to add your symbols!).
$84 increased by 7% is $89.88!
-6(6)(-3){2(-3)+(2(6)-3(3)}
108{-6+3}
108(-3)
-324

Answer:
300 calories in 8 ounces
Step-by-step explanation:
To find the amount of calories in 8 ounces we need to make the ounce amount the same. Let x equal the number of calories.
75/2=x
To get to 8 ounces we need to multiply the bottom by 4. and what we do to the bottom we do to the top.
75*4/2*4=x
multiply
300/8=x
There are 300 calories in 8 ounces.
