Answer:

270 socks/month over 5 months

Step-by-step explanation:

To calculate this total number of outgrown socks, we multiply (250 socks/mo) by 3 months (Jan., Feb. and Mar.) and then (300 socks/month) by 2 months (Apr., May):

Total average number of socks per month:

Total number of socks / number of months:

3(250) + 2(300)     socks

----------------------- * ----------- = 270 socks/month over 5 months

        5                       mo
