Answer:
hours open 3 = number of customers in the store 27 and
hours open 4 = number of customers in the store 32
Explanation:
To finish the table, remember that for every hour the store is open, 13 customers enter, and 8 customers leave, giving an overall change of 5 additional customers every hour.
Hours Open Number of Customers
In the Store
0 12
1 17
2 22
3 27
4 32
The 12 customers at the door when it opened represents the y-intercept and the 5 additional customers per hour represents the rate of change (or slope). The x-values represent the number of hours the store is open.
Therefore, the equation that represents the number of customers in the store is y = 5x + 12.
