A certain airline charges a service fee of 7% for each plane ticket purchased. What is the total price the airline charges for a $320 plane ticket?

Answer: $342.40Step-by-step explanation:There are two ways you can solve this problem:Simply turning the percentage to a decimal and multiplying it to the $320.In the picture provided the method at the top represents you multiplying $320 x .07, You might be wondering “why .07 instead of 7%?” Well, if you were turning this number from a percent to a decimal you would shift the decimal point over to the left 2 times. And so multiplying $320 x .07 = 22.4 or 22.40. Either way works but without the zero is the way you should write it. And you would add 22.4 to $320 and get $342.40.Also in the picture provided I used the method of proportions.Where the total is $320 in this case which you would put next to 100% as 100% means complete or the total. And you would put 7% above 100%. Then, proceed to cross multiply $320 by 7 and it will give you, 2240. Then, you divide it by 100. When you divide it you get 22.40. Then you would add it to $320 and get 342.40.
