your local gas stations are having a price war during the past seven days they have lowered the price of regular gas by $0.2 eac

Serga [27]

<h2>Answer with explanation:</h2>

Let x denotes the number of days and y denotes the total change in gas price ( in dollars).

Given : During the past seven days the price of regular gas is decreased by $0.2 each day.

Rate of decrease =$0.2 per day

Then , Total change in gas price = Rate of decrease x Number of days

i.e. $y= 0.2 \times x$

i.e. $y=0.2x$ (1)

To find the total change in gas price in 7 days , we put x= 7 in (1) , we get

$y=0.2(7)=1.4$

Hence, the total change in gas price in 7 days = $1.4
