The correct answer is1D k 2D k 3Dk
The answer you are looking for would be D. $3
This is found by divding 50 (number of students) by 5 (number of students per chaperone). This shows there are 10 chaperones.
Multiply 10 and 45 (cost of adult tickets) to get $450. Then multiply 50 and 30 (cost of student tickets) to get $1,500.
Next you'd add 1,500 and 450 together to show the total ticket cost, which is $1,950. Since the organization raised $1,800 already, you'd subtract it from $1,950, to get $150.
Finally, divide $150 by 50 to show how much each student pays.
I hope this helps!
Answer:
20 seconds
Step-by-step explanation:
30 is where the E point is at while 10 is where D-point at.subtract these 2 and youll get 20
Let x = ribeye steak cost, y = grilled salmon cost. With this we set up two equations:
17x + 16y = 571.16
21x + 8y = 583.22
We must now pick which dinner we could like to find the cost of first. I choose the ribeyes. To do so, I'm going to divide the first equation by - 2. I will explain why:
- 8.5x - 8y = - 285.58
21x + 8y = 571.16
Now we combine like terms. Notice that the y-variables cancel each other out. This why I divided by - 2. It causes this cancellation leaving us with only one variable to solve. This gives us:
12.5x = 297.64
Divide both sides by 12.5 to isolate variable x.
x = 23.8112 or x ≈ 23.81. I round two decimal points since we're dealing with money.
Now, we plug this cost into either of the two equations and solve for variable y. I'll use the first one.
17(23.81) + 16y = 571.16
404.77 + 16y = 571.16
Subtract 404.77 from both sides to isolate the variable and its coefficient.
16y = 166.37
Divide by 16 on both sides to get rid of the coefficient
y ≈ 10.3993 or y ≈ 10.40 since we're dealing with money.
Cost of ribeye steak -- $23.81
Cost of grilled salmon -- $10.40
