Question

In 1992, Jason bought a gallon of gas for $1.23. Yesterday, he bought a gallon of gas for $2.17. 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. 23.6% B. 56.7% C. 76.4% D. 43.3%

Answer 1

What percentage of 1.23 is 2.17? The amount over 100% will be the increase:

`2.17 = \huge \text((x)/(100)\huge \text )(1.23)`

`x =( 2.17(100))/(1.23)`

`x = 176.4\%`

The increase is 76.4%
