Answer 2

Answer:

A) 62.7344

Step-by-step explanation:

Since the number of sales call is larger than the number of items sold,

therefore, the sales call is 'x' and the 'number fo items sold is 'y'.

(Note that the coefeficient of x = 0.2608, which is less than 1.)

Put the value of x = 164 in the equation and find out 'y'
