Question

if it cost $14 to fill a gas tank in 2020, how much would it have cost to fill the same tank in 1970?
average gasoline prices (per gallon)

it would have cost $\square$ in 1970.
(round to the nearest cent as needed.)

Explanation:

Step1: Identify the percentage for 1970

From the table, the price in 1970 is 16.6% of the 2020 price.

Step2: Calculate the 1970 cost

The 2020 cost is $14. So, the 1970 cost is $14 16.6% = $14 0.166.
$14 * 0.166 = 2.324$

Step3: Round to nearest cent

Rounding 2.324 to the nearest cent gives $2.32.

Answer:

2.32
