Algebra 1 a car can travel 78 miles on 13 gallons of gasoline. How much gasoline will it need to go 150 miles
a. 13
b. 78
c. 50
d. 25

D

Step-by-step explanation:

First we need to find out how many miles we can travel using 1 gallon of gasoline. We can easily find that by dividing 78/13 which equals 6. Now we just need to multiply all of the given answers by 6. To be reasonable, since we already know 13*6=78, we should look at the next smallest number and go up from there.

The next smallest number given is 25. 25*6=150.

Hope this helps!! <3 :)

The answer is: $608.33.

The given information is:

The total amount is given by the following formula:

Where,

P is the starting amount

i, is the interest rate in percentage.

t, is the time.

We must remember that we cannot work with percentages,  so we need to convert the given percentage into a real number by dividing it into 100

So,

Now, substituting the given information into the formula, we have:

So, the total amount after 5 years when she pays off the loan is $608.33.

Have a nice day!
