Answer:
270 pairs of socks
Step-by-step explanation:
We need to know how much Vanya grew in total during the 5 months. However, in the statement they give us are the average amounts for 2 and 3 months. So:
If Vanya grew an average of 250 pairs of socks for 3 months, then a total of:
250 * 3 = 750 pairs of socks in 3 months.
If Vaya then grew an average of 300 pairs of socks for 2 months, then you grew a total of:
300 * 2 = 600
In the 5 months, Vanya grew a total of 750 +600 = 1350 pairs of socks.
We already have the total amount of pairs of socks that Vanya grew. Now, to find the average during the 5 months, we divide the total by 5.
1350/5 = 270
Vanya grew an average of 270 pairs of socks during the 5 months.
