It costs $80 each day to operate the restaurant and $40 dollars a day for each employee. Use the following inequality to determine how many employees the manager can afford for the day, at most:

40x + 80 ≤ 400
a)x ≥ 8
b)x ≥ 12
c)x ≤ 8
d)x ≤ 12

For f(x)=2x+3 and g(x)=x^2- 8 find (f+g) (x)

Suppose you are an avid reader and are looking to save money on the cost of books instead of paying about $20 for each book, you decide to look into purchasing a kindle for $120 you can purchase e-books for about $5 each 1. find the slope-intercept equation for the cost of the hard copy of books using x to represent the number of books 2. find the slope-intercept equation for the cost of the kindle with cost of e-books using x to represent the number of books

If a company produces x units of an item at a cost of $35 apiece the function c=35x is a of the total production costs
