The percent increase is 12.5%, 800 multiplied by 0.125 equals 100 and 100+800=900.
The original price of the sweater is $80 which is 100% of the price.
If the price is reduced by 25%, then the new price is 75% of the original price since 100% - 25% = 75%.
Now we need to find 75% of $80.
To find a percent of a number, multiply the percent by the number.
To convert a percent into a decimal, divide the percent by 100 which is the same as moving the decimal point two places to the left.
Here's how to change 75% into a decimal.
75% = 75/100 = 0.75
Here's how you calculate 75% of $80.
75% of $80 =
= 75% * 80
= 0.75 * $80
= $60
Answer: The sale price is $60.

Answer:
B
Step-by-step explanation:
The standard form of a circle is
where h and k are the center and x and y are the coordinates you're given. We need to solve for the radius to finish this off correctly. Filling in, we have
and
, giving us that
. Therefore, our equation is
