To solve this, we must set up a
Systems of Equations problem
Let's say
C stands for
Coach seats bought and
S stands for
sleeper cars bought
Here are our equations we have enough information to make.
c + s = 93 115c + 290s = $20,320 Lets solve for Coach seats first
To do that we need a value for s
In the first equation,
s = 93 - cLets plug that in for S in the second equation
115c + 290(93 - c) = $20,320 Distribute and simplify
115c + 26,970 - 290c = $20,320
Combine like terms
-175c + 26,970 = $20,320
-175c = -6650
divide
c =
c = 38We just found out 38 coach seats were bought.
Plug in 38 for C in this equation ⇒ 115c + 290s = $20,320 to find S
115(38) + 290s = $20,320 Distribute and Simplify
4,370 + 290s = $20,320
290s = $15,950
Divide
S =
S = 55We just completed the problem!
38 Coach seats were bought and 55 Sleeper car seats were bought.

Step-by-step explanation:
Answer:
8x^2 + 6x + 36xy^2 + 24y^2
Step-by-step explanation:
First, multiply the two terms inside the second set of parentheses by-2x; we get 8x^2 + 6x.
Next, multiply the same two terms by -9y^2; we get 36xy^2 + 24y^2.
Now add these products together:
8x^2 + 6x + 36xy^2 + 24y^2 This is the desired product.
24 video games.
First you subtract $72 from $1,128 then you divide $43 from $1,056 and you get 24.5581395
So the most video games jasmine can buy is 24.
Decimal pt after 3 digits in first number so 3 digits in product.
