To write and simplify polynomial expression

Answer to Problem 28PPS

  $10l+2m+14s$

Explanation of Solution

Given information:

Cost of medium pizza = $m

Cost of large pizza = $l

Cost of sub = $s

Calculation:

According to question

Order by class 1=4 large pizzas, 2 medium pizzas and 6 subs

Order by class 1=6 large pizzas and 8 subs

Total amount spent= cost of order by class1+ cost of order by class2

  $\begin{array}{l}=(4l+2m+6s)+(6l+8s)\\ =4l+2m+6s+6l+8s\\ =10l+2m+14s\end{array}$

Expression is: $10l+2m+14s$
