I don't know if it is correct but here goes nothing 8*(d-3)
Answer:
Step-by-step explanation:
h e a t e r
keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

well then, so since this equation has that slope therefore

so we're really looking for the equation of a line whose slope is 8/5 and runs through (10,10)

The answer is $630.57
You first need to add both the borrowed money and the interest then divide it all by 30
$16,000+$2,917.10= $18917.10
$18917.10/30= $630.57
