Question

A local deli kept track of the sandwiches ifsold for three months. The polynomialbelow models the number of sandwichessold, where s represents the number of days.Ham & Cheese: 4s^3 + 28s² + 33s + 250Turkey & Cheese: -7s² + 32s + 180Write a polynomial that models the total number ofsandwiches that were sold

Answer 1

Step 1

Given;

`\begin{gathered} Ham\text{ \& cheese- 4s}^3+28s^2+33s+250 \\ Turkey\text{ \$ Cheese; -7s}^2+32s+180 \end{gathered}`

Required; Write a polynomial that models the total number of sandwiches that were sold.

Step 2

Add both polynomials

`\begin{gathered} (\text{4s}^3+28s^2+33s+250)+(\text{ -7s}^2+32s+180) \\ =4s^3+21s^2+65s+430 \end{gathered}`

Answer;

`=4s^3+21s^2+65s+430`
