James

James is painting a fence. If he painted 16 planks per day instead of 14, he would finish one day earlier. How many planks does the fence have in total?

Final Answer:

n =  112

Step-by-step explanation:


14 t = n
16 ( t-1) = n

14·t = n
16·( t-1) = n

n-14t = 0
n-16t = -16

Row 2 - Row 1 → Row 2
n-14t = 0
-2t = -16


t = -16/-2 = 8
n = 0+14t = 0+14 · 8 = 112

n = 112
t = 8
