the answer is C.
12a -18s =36
(12 adult tickets= 12a) - (18 student tickets =18s) =$36
For this case we are going to assume that Nina wrote:
3/4 (1440) + 295.25 + (-33.50).
The expression is correct since we have:
ticket sales were three-fourths as much as yesterday. That means
3/4 (1440)
food sales were down by $ 33.50, that means:
295.25 + (-33.50)
Therefore, today's sales were:
3/4 (1440) + 295.25 + (-33.50).
answer
Nina's expression is correct
Step-by-step explanation:
<u>to show how many tickets were sold:</u>
x = upper floor tickets
y = main floor tickets
x + y = 2000
<u>to show total amount of revenue:</u>
25x + 40y = 62,000
<u>Finding answer using both equations:</u>
x + y = 2000
multiply each side by 25
25x + 25y = 2000 × 25
25x + 25y = 50,000
25x + 40y = 62,000
-
25x + 25y = 50,000
-----------------------------------
15y = 12,000
^ this is column subtraction
<em>^ this column subtraction is done to isolate y so we can work with one value rather than 2</em>
15y = 12,000
divide each side by 15
12,000 ÷ 15 = 800
y = 800
x + y = 2000
x + 800 = 2000
x = 1200
Therefore 1200 upper-level tickets were sold
800 main floor tickets were sold
Answer:
300 programs
Step-by-step explanation:
Let’s work with cents to make this easier. We convert the $12 to cents, making 1200 cents
Let the number of copies Alden printed be x. His total printing cost would be x * 54 = 54x cents.
He sold at 75 cents each and still had left 100 copies. This means his total sale would be (x - 100)75
He lost $12 on the venture. This means his cost price minus his selling price is $12 since it’s a loss.
Computing this:
54x - 75(x - 100) = 1200
54x - 75x + 7500 = 1200
-21x = 1200 - 7500
-21x = -6,300
x = 6300/21 = 300 programs
