Describe a meal you would order and include the cost of each item. Calculate the total cost of the meal, which includes a tax of 7.5% on the food, a 1% tip for the valet who parked your car, and a 12% tip for the server. Next, calculate what would happen if you instead invested the total cost of the meal in a savings account with 4% simple interest credited monthly and left it in the account for a year.

Use addition and subtraction to simplify the following polynomials. a. add polynomials: (3 – 4x + 8x^2) + (–6 + 2x – 5x^2) step 1: rewrite the polynomials without the parentheses. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial. b. subtract polynomials: (3x – 5 – 7x^2) – (–2 + 6x^2 – 5x) step 1: rewrite the polynomials without the parentheses. remember to multiply each term in the second parentheses by –1. show your work. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial.
