The cost function, in dollars, for producing microchips is given by C(m) = 1.35m + 200, where x is the number of microchips produced. The number of microchips produced is M(t) = 20t, where t is the number of hours of production. A. Give the cost, C, as a function of time, t-- find C(M(t)). B. Find the cost of production run that lasts 8 hours. C. How many microchips are produced in 8 hours.

good luck!

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
