For this case we have the following rule of three:
92 pairs of jeans are sold in two months, then:
92 pairs ----------> 2 months
You want to know how many you would sell in 3 months:
x pairs ------------> 3 months
So:
92 pairs ----------> 2 months
x pairs ------------> 3 months
![x = \frac {3 * 92} {2}\\x = 138](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%20%7B3%20%2A%2092%7D%20%7B2%7D%5C%5Cx%20%3D%20138)
Thus, for three months at least 138 pairs of jeans will have been sold
Answer:
138
