Can someone explain how to do this step by step? and give the formula

two stores sell the same television for the same original price. store a advertises that the television is on sale for 30% off the original price. store b advertises that it is reducing the television’s price by $250. when allison compares the sale prices of the television in both stores, she concludes that the sale prices are equal.

let p represent the television’s original price.

which equation models this situation?

0.3p = p + 250

0.7(p−250)=p0.7(p−250)=p

0.7p=p−2500.7p=p−250

0.3=p−250
