The George A Stinson is the second largest freighter on the Great Lakes. Normally, it carries 57,000 tons of taconite each voyage between Superior, Wisconsin , and Detroit, Michigan. Now, due to lower lake levels, it can only carry 55,000 tons per trip. At an average cost of $5 per ton, how much revenue is lost per trip?

i really dont know

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
