At the gas station, each liter of gas costs \$3$3dollar sign, 3, but there's a promotion that for every beverage you purchase you save \$0.20$0.20dollar sign, 0, point, 20 on gas. is your total savings on gas proportional to the number of beverages you purchase?

Yes , your total savings on gas proportional to the number of beverages you purchases.

As for every beverage purchased , there is a saving of $0.20

If we show by an equation , where savings is s , and number of beverages is b

Than

s = 0.20 b

Yes, there is a proportional relationship between the two.

Step-by-step explanation:

Given is :

Each liter of gas costs is $3, but with purchase of 1 beverage, we save $0.20 on gas. Similarly, if we purchase 2 beverage we save $0.40, If we purchase 3 beverages, we save $0.60 on gas.

Here, we can see that with each beverage, the savings on the gas is increasing. So, its proportional to each other.

If we want to show the relationship:

Let us suppose money saved be = x

Let us suppose the beverages purchased be = b

So,

Hence, yes the total savings on gas is proportional to the number of beverages you purchase.
