Answer: Model A: 6, Model B: 3
Step-by-step explanation:
Model A can pring 50 books per day so since you have 6 of those, the Model A printing presses would pring 300 per day (50 x 6). If you have 6 of the Model A printing presses, that means you have 3 Model B printing presses because there is a total of 9 printing presses. Therefore, you would multiply 3 by 30 which is 90 because the Model B ones can pring 30 per day.
390 (books total) = (50 x 6) + (30 x 3)
390 = 300 + 90
Answer:

f^-1 represents the number of hours the bacteria developed
Step-by-step explanation:

To find inverse of a function , replace f(t) with y

replace t with y and y with x

solve for y
divide both sides by 100

take ln on both sides

divide both sides by ln

multiply by 3 on both sides

Replace x with t and y with f^-1

f^-1 represents the number of hours the bacteria developed
