**1. Find the sales necessary to break even (R=C) if the cost C of producing x units is**

Given....

## Homework Equations

C = 5.5((sqrt(x)) + 10,000 (Cost Equation).

R = 3.29x (Revenue Equation).

## The Attempt at a Solution

I thought about what R = C means, your output is equivalent to your input, no? So I followed (R=C) and set the two equations equal; after calculating I come across a quadratic which isn't factorable, so I use the quadratic forumla which doesn't yield answers close to the actual value for x which is approximately equal to 3133 units.

## Homework Statement

The next problem asks me about a Conveyor design...

"

*A moving conveyor is built to rise 1 meter for each 3 meters of horizontal change*

Find:

A). The slope of the conveyor

B). Suppose the Conveyor runs between two floors in a factory. Find the length of the conveyor if the vertical distance between floors is 10 feet.

## Homework Equations

m = (y_2 - y_1) / (x_2 - x_1) The slope forumla ( sorry I haven't been aquainted with LaTeX yet, and I didn't have any of the greek letters, delta, copied.)

## The Attempt at a Solution

Well, slope is a measure of vertical rise relative to horizontal shifts so the slope, m, is 1 meter up for every 3 meters right. When I make an attempt at the second problem I just think the distance is 20...I know it's completely wrong but i'm at a loss when trying to interperet some of these questions. Thank you all for your time in advance.
