Ответ:
$937
Step-by-step explanation:
P(1-20/100)=750- 1 is the object the you take away the percentage that is in
fraction form
P(1-.2)=75-take it from fraction form to decimal form
P(.8)=750-this is the final product of the equation above
750/.8-Take the current price and the decimal and divide
75000/80- take the .8 and add two 0's to get the whole accurate amount
937.5-Price before the price fell
Sorry I'm not the best at explaining things hoped this helped!
