Algebra 1
goblinko [34]

Answer:

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 :)

Postage costs are $.22 for the 1st ounce and $.70 for each additional ounce what is the cost of postage for letter weighing 3
Maurinko [17]

Answer:

The cost of the postage for the letter weighing 3 ounces will be $1.62

Step-by-step explanation:

From the question, we know that the first ounce will cost $0.22 and any additional ounces will cost $0.70, therefore, we can make the following equation where "c" is the total cost of the postage and "a" will be the total weight of the letter in ounces.

c = 0.22 + (0.70)(a - 1)

(we subtract 1 from "a" because for the first ounce we will pay $0.22 instead of $0.70)

Now we just solve the equation by substituting "a" with 3, and we get...

c = 0.22 + (0.70)(a - 1)

c = 0.22 + (0.70)(3 - 1)

c = 0.22 + (0.70)(2)

c = 0.22 + 1.40

c = $1.62

Therefore, the cost of the postage for the letter weighing 3 ounces will be $1.62.
