Question

Can someone please help me with this?

Answer 1

Answer:

y = 0.02x

$0.14

Step-by-step explanation:

Let

x = number of days the station was lowering the price of the gas

y = total change in gas price (after x days)

Each day the station lowered the price by $0.02, then after x days the price was lowered by $0.02x. Thus,

y = 0.02x

After 7 days the total change in gas price is

$\ 0.02\cdot 7=\ 0.14$
