g100num [7]

Answer:

we must get more than 4 digs in the remaining 3 games break record of 20

Step-by-step explanation:

given data

current volleyball season = 16 digs

games left in the season = 3

previous record = 20 digs

solution

we consider here the number of digs x that must get in the remaining 3 games to break your record

so for break previous record of 20 digs, we have to get more than 20

so 16 digs must add to x to greater than 20

x + 16 ≥ 20 ...............................1

so x will be

x ≥ 20 - 16

x ≥ 4

so that we must get more than 4 digs in the remaining 3 games break record of 20
