In 1992, Jason bought a gallon of gas for $1.20. Yesterday, he bought a gallon of gas for $2.22. What is the percentage increase of the price of a gallon of gas from 1992 to yesterday? If necessary, round to the nearest tenth of a percent. A.
54.1%
B.
15%
C.
45.9%
D.
85%

A.

Step-by-step explanation:

(I'm not sure if this is right so let me know)

If you divide 1.20 by 2.22 it comes out as 0.5405. If you take this and round, you get 0.541. After this, to make it a percentage, you move the decimal 2 places left, which comes out as 54.1%

Hope this helps!

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.
