The carson’s are on a road trip they paid $62.70 for 16 1/2 gallons of gasoline part 1-find the price of gasoline per gallon show your work part 2-give an example of a cost and amount that would make the gasoline have a rate of $3.49 per gallon

$3.92  per gallon

10 gallons of gas at $3.49 a gallon will cost $34.90

Step-by-step explanation:

To find the price per gallon, we take the total cost, and divide by the number of gallons.  I will change 16 1/2 to a decimal for ease of math calculations.  

16 1/2 = 16.5

cost/gallons

$62.70/16.5

3.91875

Since we are working with money, we round to the nearest cent

$3.92  per gallon

To find the  total cost, we multiply the cost per gallon times the number of gallons.  We have a cost per gallon of $3.49.  If we multiply by 10 gallons

cost = $3.49 * 10

        $34.90

10 gallons of gas at $3.49 a gallon will cost $34.90

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
