250 lunches are produced by the small business in last week.
Step-by-step explanation:
It is given that,
The function relating these two factors x and y is given as y = 2.1x + 75
To find the value of x :
Substitute y= 600 in the given function,
β 600 = 2.1x + 75
β 2.1x = 600 - 75
β x = 525 / 2.1
β x = 250
Therefore, the lunches prepared last week is 250.
