Final answer:
Alan's total pay without selling any items is $3,600, which is obtained by plugging in x=0 into the equation y=45x+3600. Therefore correct option is B
Step-by-step explanation:
The question asks what Alan's total pay is if he doesn't sell any items.
Using the provided equation y = 45x + 3600, we plug in x=0 since no items are sold. Therefore, the equation simplifies to y = 3600. This means that Alan's total pay, without selling any items, is $3,600.
The value is obtained by understanding that the equation represents a linear relationship between the number of items sold (x) and total pay (y), where 3600 is the y-intercept, representing Alan's fixed salary irrespective of the sales.
