I believe the answer is 20.

C= 15n + 85

$385= 15n+85

$385-85= 300

300/15= 20

20 watches are made since 385 = 15n + 85. 385 - 85 is 300 and 300 divides by 15 is 20.

If we look at where it is now, we would have multiplied the x and y values by 1/2. since we are working backwards, lets multiply by 2 instead...giving us the vertex for the pre-image....

J is now (0, -2)      multiply by 2
J was     (0, -4)
