aksik [14]

Answer:

$0.24

Step-by-step explanation:

Given:

At full price, Melvin would  pay for per liter of gasoline =  $1.679

Using his loyalty card, Melvin only pays = $1.439

Question asked:

How much less does Melvin pay per liter using his loyalty card?

At full price, Melvin would  pay for per liter of gasoline =  $1.679

Using his loyalty card, Melvin only pays = $1.439

To find that that how much less amount Melvin pay for per liter of gasoline using his loyalty card, we will subtract the payment using loyalty card from payment without using loyalty card.

$1.679 -  $1.439 = $0.24

Therefore, $0.24 less amount Melvin pay for per liter of gasoline using his loyalty card.
