Answer:
Part A: 299 + 45A + 30B + 50c
Part B: 569 (or 570 if you round it up)
Step-by-step explanation:
Part A:
Because there is no variable for the number of PlayStation 4s, let's assume that there is only one. That will be 299.
If A is the number of wireless controllers and each wireless controller is worth 45 dollars each, the price for the wireless controller(s) is 45A.
If B is the number of wireless controller charging stations and each wireless controller charging station cost 30 dollars, then the price of the wireless controller charging station(s) is 30B
If C is the number of games and each game cost 50 dollars, then the price of the game(s) is 50C
Put that all together, and we get 299 + 45A + 30B + 50c.
Part B:
Let's plug the numbers into the formula.
A = 2
B = 1
C = 3

Answer:A
Step-by-step explanation:
Answer:
The system that models the situation is:

The solution is:
(9, 6)
Step-by-step explanation:
We must write the equations as indicated in the problem.
The sum of twice a number and another number is 24
<em>a number:</em> x
<em>other number:</em> y
Then

The difference of twice the first number and the other number is 12
<em>first number: </em> x
<em>other number:</em> y
Then:

The system that models the situation is:

To solve the system we add both equations to find the value of x

---------------------


The solution is:
(9, 6)
Remember
∛(xy)=(∛x)(∛y)
3rd power
factor inside and group
384=2*2*2*2*2*2*2*3=2^3*2^3*2*3=2^3*2^3*6
∛384=(∛2^3)(∛2^3)(∛6)=(2)(2)(∛6)=4∛6
