One-twelve 17223

The company produced 91800 pairs of shoes in the first half of the year, and in the second half, they increased their production by one-twelve. How many pairs of shoes did they produce in the year's second half, and how many per year? How many shoes was that?

Correct answer:

b =  99450
s =  191250
k =  382500

Step-by-step explanation:

$$\begin{gathered} a=91800 \\ b=a+a/12=91800+91800/12=99450 \end{gathered}$$

$s=a+b=91800+99450=191250$

$k=2\cdot s=2\cdot 191250=382500$
