The formula for simple interest is: [tex]A = P(1 + rt)[/tex]
[tex]R=12[/tex]
We are going to convert the percent (12) into a decimal.
[tex]r = R/100 = 12/100 = 0.12[/tex]
Then, we are going to put the months into years.
[tex]3 / 12 = 0.25[/tex]
Let's plug in the values:
[tex]A = 175.54(1 + (0.12 * 0.25)) = 180.8062 [/tex]
[tex]A = 180.81[/tex]
The total amount paid for the trip is $180.81
Have a nice day! :)

What is interest?
Interest can be defined as the amount of money a lender receives for lending out money.
Given that rate of interest is 12% and charges are paid after 3 months.
So the time period is converted into years as below.
T = [tex]3\times 4[/tex]
T = 12 months = 1 year.
The rate of interest for a year is,
R = 12/ 4
R = 3 %
The principal amount is the sum of tickets, food, and gas.
P = 67.70 + 62.34+ 45.50
P = 175.54
The amount is calculated as given below.
[tex]A = P(1 + R)^T[/tex]
[tex]A=175.54(1+0.03)^1[/tex]
A = 180.80
Hence we can conclude that the total amount paid for the trip is 180.80.
