Answer: I=sqrt(P/R)
Step-by-step explanation:
R=p/I^2
Multiple l squared on both sides...
(I^2) R=p/l^2 (l^2)
R(I^2)=p
Separate I by dividing both sides by R...
I^2=p/R
Square root both sides...
I=sqrt(P/R)
30$ originally - 21$ paid = 9$ discount
> divide the discount by the original price, multiply by 100 to get the percent decrease.
100 x (9$ / 30$) = 30% discount
> So the shoes where on sale for 30% off the original price.
for the equation:
100 x (30-21)/30 = % decrease
