5% of 235 is: 235*(5/100)= 235/20 = 11,75 or 5% of 470 is: 470/20 = 23,5
Total cost = 2*(235 + 11,75) = 2*246,75 = 493,5 or Total cost = 470 + 23,5 = 493,5
Answer:
Step-by-step explanation:
The equation is y=mx+b.
In this case, you plug in 3 for b, because b represents the y-intercept and the y-intercept is (0,3).
To figure out the slope, the equation is y-y/x-x, so it would be 8-3/1-0, which leves us with 5.
M represents the slope so your answer is:
Y=5x+3
