Comments on: A furniture manufacturer produces chairs. It costs R2 200 to manufacture 100 chairs in one day, and R4800 to? http://furniturebarstool.net/a-furniture-manufacturer-produces-chairs-it-costs-r2-200-to-manufacture-100-chairs-in-one-day-and-r4800-to.php Tue, 07 Feb 2012 02:17:40 +0000 hourly 1 http://wordpress.org/?v=3.2.1 By: pharmonic http://furniturebarstool.net/a-furniture-manufacturer-produces-chairs-it-costs-r2-200-to-manufacture-100-chairs-in-one-day-and-r4800-to.php/comment-page-1#comment-2473 pharmonic Mon, 02 Nov 2009 18:59:51 +0000 http://furniturebarstool.net/a-furniture-manufacturer-produces-chairs-it-costs-r2-200-to-manufacture-100-chairs-in-one-day-and-r4800-to.php#comment-2473 A. is true because 13*100+900=2200 and 13*300+900=4800 B. is true, the y-intercept is when x=0, i.e. when you produce nothing, which gives the fixed daily operating cost C. is not true, because due to A. the equation is given by y=13*x+900 and then to make 200 chairs it will cost 13*200 + 900 = 3500 Thus 4. Only A and B is the correct answer. A. is true because 13*100+900=2200 and 13*300+900=4800

B. is true, the y-intercept is when x=0, i.e. when you produce nothing, which gives the fixed daily operating cost

C. is not true, because due to A. the equation is given by y=13*x+900 and then to make 200 chairs it will cost 13*200 + 900 = 3500

Thus 4. Only A and B is the correct answer.

The y-intercept is where the line touches the y-axis. In other words, the y-intercept is the y-value when x = 0. When x = 0, that means no chairs are made, but there is still an associated cost: y = 13 * 0 + 900 y = 900 Statement B is TRUE. To test statement C, since we know statement A is true, just plug in 4400 and 200: 4400 = 13 * 200 + 900 4400 = 2600 + 900 4400 = 3500...FALSE Statement C is FALSE. The correct answer is 4. Only A and B. Test statement A by plugging in values:

2200 = 13 * 100 + 900

2200 = 1300 + 900…TRUE

4800 = 13 * 300 + 900

4800 = 3900 + 900…TRUE

Statement A is TRUE.

The y-intercept is where the line touches the y-axis. In other words, the y-intercept is the y-value when x = 0. When x = 0, that means no chairs are made, but there is still an associated cost:

y = 13 * 0 + 900

y = 900

Statement B is TRUE.

To test statement C, since we know statement A is true, just plug in 4400 and 200:

4400 = 13 * 200 + 900

4400 = 2600 + 900

4400 = 3500…FALSE

Statement C is FALSE.

The correct answer is 4. Only A and B.
