8.75x+10(x+6)=165

18.75x+60=165

you would add those to get 650

Now how many numbers did you add?

Why is the total cost of fuel when a driver averages 8 miles per gallon..The cost of fuel is .83 cents a gallon..The drivers dis
Allushta [10]

Answer:

The total cost of the petrol is 2.075 cents.

Step-by-step explanation:

The cost of per gallon petrol = 0.83

Drive per gallon = 8 miles

Here, total distance traveled = 20 miles.

So, the total petrol used for 20 miles = (20 / 8) gallons

= 2.5 gallons

Now, cost of petrol per gallon = 0.83 cents

So, total cost of petrol = 0.83 x 2.5  = 2.075 cents

Hence, the total cost of the petrol is 2.075 cents.
