The last one is the only one that will work.
For the first one the y intercept is when x = 0. The point would be 0,4
The second one gives a point of (4,0)
The third one is nonsense. (4,4) is not on this line.
($3756/100)(100+12)/100
$37.56(1.12)
$42.0672
$42.07 (to nearest cent)

100 times, because 5 times 100 equals 500
