In C++

 #include #include #include // for fixed #include // for setprecision using namespace std; int main() { double price; cout > price; // we're living in an alternate universe where there are no pennies or nickels, // so everything is rounded to the nearest 10 cents // Your program will calculate 7.75% tax, *rounded to the nearest dime* // Come to office hours and I'll give you a hint! // FIXME: print the following on separate lines // (all #s rounded to the nearest 2 decimal places): // 1. the price // 2. the (rounded) sales tax calculated for the price, with a '+' at the front // 3. a line with 10 '=' characters // 4. the total price // // Some of these lines will begin with a space or a '+' character--see the example // in the write-up. return 0; }

Part 3: Write a sales tax calculator for a world without pennies or nickels For this program, you will get an input price from the user, and then you will calculate 7.75% sales tax rounded to the nearest dime. You'll have to think a little bit about how you can use the round() function to round a number to the nearest tenth. Take a look at the library documentation for more information on the round() function. After you've calculated the sales tax, you'll output the total price as well, and the autograder will be looking for a specific kind of formatting. Here are some examples of my solution's output to give you an idea of how your formatting should look: solution ./sales Tax Enter the price: 12.20 $12.20 + $0.90 $13.10 solution ./sales Tax Enter the price: 47.30 $47.30 + $3.70 $51.00 solution ./sales Tax Enter the price: 54.30 $54.30 + $4.20 $58.50 solution
