Multiply 324 by

You get 63
4,200 meters

Hope this helps good luck tho :)
<h3>
Explanation:</h3>
In the graph x-coordinate represents the number of wind chimes sold and y-coordinate represents the profit Madison earned. If a point is below the x-axis, means it has negative y-coordinate than it represents loss. Points above x-axis should have x-coordinate more than 6 as stated in the question that she started earning profit after selling her first 6 wind chimes. All the points having x-coordinate less than 6 should lie on or below the x-axis.
By the above statement point B is completely wrong. Point C and Point A are also wrong as they both x-coordinate more than 6 but still they are below x-axis.
Point D is the makes most sense here as it has x-coordinate more than 6 and it is above x-axis. This means that when Madison sold 7 wind chimes she was in a profit of $3.75.
Answer:
Step-by-step explanation:
orginal :$240
new/sale: $180
Percentage of Change:
(V2−V1)|V1|×100
=(180−240)|240|×100
=−60240×100
=−0.25×100
=−25%change
=25%decrease
