Respuesta :
If $3.53 is 100% then 3.05 is 86.5%
100%–86.4% is a 13.6% decrease in price
100%–86.4% is a 13.6% decrease in price
The percent change in the cost of a gallon of gas is 13.59 %
Solution:
We have been given the data of cost of Gas in two months these are May and September
The cost of Gas in month of may is $3.53 per gallon
The cost of Gas in month of September is $3.05 per gallon
We have to determine the percentage change in the cost of gas
Difference in cost of gas = 3.53 – 3.05= 0.48
[tex]\% \text { change in cost of gas }=\frac{\text { Difference in cost of gas }}{\text { original price }} \times 100[/tex]
[tex]\% \text { change in cost of gas }=\frac{0.48}{3.53} \times 100[/tex]
% change in cost of gas = 13.59 %
So, the price of the Gas was decreased by 13.59% from may to september
