Step-by-step explanation:
In the graph we can clearly see a directly proportional relationship between the increase in customers as the weeks increase, a double increase for each week;
For example:
-For the second week the number of clients is double than in the first week, this pattern of increase, that is, twice a week, remains constant.
-Following the pattern of increases in clients per week, we can reach the conclusion that surely by week 7 the increase in clients will be 13.
ANSWER:
Therefore the answer would be that by the seventh week there will be 13 clients.
