I do not understand ???????????????????
Answer:
Model A is 9
Model B is 5
Step-by-step explanation:
At Lisa's printing Company LLC there are two kinds of printing presses model.
Let x = the number of model A printing press.
Let y = the number of the model B printing press.
model A can print 70 bucks per day and model B can print 55 bucks per day.
The total number of both models prints 905 bucks per day.
This means
70x + 55y = 905 - - - - - - - - -1
The company owns 14 total printing presses. This means
x + y = 14 - - - - - - - - - -2
x = 14-y
Put x = 14-y in equation 1
70(14-y) + 55y = 905
980 -70y + 55y = 905
-15y = 905-980= -75
y = -75 / -15= 5
x = 14-y = 14-5
= 9
Answer:
y =-3000x +12000
Step-by-step explanation:
answer is
1) 12000 is the constant therefore when the number of hours is 0 the tickets are 12000
2) the number of tickets (y) are reducing by 3000 for each hour(x). thus the coefficient of variable x should be -3000 (negative because it is reducing)
answer: -5x+12=20
-12 -12
-5x/-5= 8/-5
x= -1.6
