Answer: - $ 0.14

Step-by-step explanation:

t

be the total change in the price of gas, what we are solving for in this problem.

d

be the number of days the prices has decreased. 7 for this problem.

c

be the change in price each day. - $0.02 for this problem (the price has been lowered so this number is negative).

The formula will be:

t = d ⋅ c

Substituting and calculating t

gives:

#t = 7 * - $0.02$

t = - $ 0.14

Over the last 7 days the price of gas has changed

- $ 0.14
