Question

A truck that can carry no more than 6500 lb is being used to transport refrigerators and upright pianos. Each refrigerator weighs 250 lb and each piano weighs 425 lb. Write and graph an inequality to show how many refrigerators and how many pianos the truck could carry.

Answer 1

Answer:

Step-by-step explanation:

Let x = the number of refrigerators

Let y = the number of upright pianos

300x%2B525y%22%22%3C=%22%226800

We graph the boundary line:

300x%2B525y%22%22=%22%226800

Divide through by 25 to simplify:

12x%2B21y%22%22=%22%22272

The intercepts are %28matrix%281%2C3%2C0%2C%22%2C%22%2C12%2620%2F21%29%29 and %28matrix%281%2C3%2C22%262%2F3%2C%22%2C%22%2C0%29%29

We draw the boundary line, and shade below it because the

origin used as a test point:

300%280%29%2B525%280%29%22%22%3C=%22%226800

0%22%22%3C=%22%226800

gives a true inequality
