You have a small business making and delivering box lunches. You calculate your average weekly cost y of producing x lunches using the function y = 2.1x + 75. Last week your cost was $600. How many lunches did you make last week?

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,

⇒ 600 = 2.1x + 75

⇒ 2.1x = 600 - 75

⇒ x = 525 / 2.1

⇒ x = 250

Therefore, the lunches prepared last week is 250.
