what is 40% off of $712.00 please explain how you got your answer as if you were teaching me how to do it.
Vikentia [17]

Answer: $284.80

look when you are trying to find the percent of a number you need to turn the percent into a decimal then multiply the decimal by the number:

1st. 40% as a decimal is 0.40 because as a fraction 40% is 40/100 so that means that 1.00 is 100 and 0.40 is 40%

2nd. Next, you do 0.40 x 712.00 = or

712.00

x  0.40

______

$284.80
