Answer:

30% of 280 is 84.

What I did to find the answer was multiply 280 by 3 then divide by 10.

I checked it with a calculator and got the same result being 84.

Likurg_2 [28]

Answer: B (slope and y-intercept)

Step-by-step explanation:

They charge $0.10 per meter, so that would be represented as y=0.10x. There is an additional fee of $25 which is the +25. The full equation is y=0.10x+25.

0.10x is the slope, and 25 is the y-intercept. Hope this helps!
