To manufacture 30 items, it costs $2700, and to manufacture 50 items, it costs $3200. If x represents the number of items manufactured and y the cost, write the cost function. a. Y= -25X + 4450
b. Y = 500 X 21,800
c. Y = 0.04X + 3198
d. Y = 25X + 1950

Step-by-step explanation:

Given

Required

Determine the linear function

We start by calculating the slope (m)

So, we have:

The equation is then calculated as:

This gives:

Make y the subject

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17
