Your local gas stations are having a price war. during the past 7 days they have lowered the price of regular gas by $0.2 each day. define a variable. then write and solve an equation to find the total change in gas price.

Let the previous price of the gas be represented by = x

Let the current price of the gas be represented by = y

As given, during the past 7 days they have lowered the price of regular gas by $0.2 each day.
