Yesterday, you paid $90 for 75 liters of gas. Today, you want to put another 15 liters of gas into your car,
How much does it cost, assuming the price has not changed?

Respuesta :

Answer:

It will cost $18 to put 15 liters of gas into your car.

Step-by-step explanation:

We have to find the unit price first, or the price per gallon. To find that, we would do $90 divided by 75 liters, which gives us $1.2 per gallon. Then, to find the price we have to pay for 15 liters, we would do 1.2 multiplied by 15, which is 18! :)
