The answer is <span>
B: x+y=700
2x+4.5y=1200
</span>
<span>x - the number of student tickets sold,
y - the number of adult tickets sold
The total number of sold tickets is 700:
x + y = 700
</span><span>Adult tickets sold for $4.50 each and student tickets cost $2.oo each. If they took in a total of $1,200:
2x + 4.50y = 1200
The system of equations is:
</span>x + y = 700
2x + 4.50y = 1200
Answer:
555 minutes
Step-by-step explanation:
So the first two line segments added together equals the full line segment. So, 8y + 5 + 7y = 13y + 25
15y + 5 = 13y + 25
2y = 20
y = 10
4 multiplied by 2 by 1 because its her hours for the weeks no other way to calculate this problem
The maximum units is 200 and , Total revenue is $8,000
<u>Step-by-step explanation:</u>
Here we have , A manufacturer finds that the revenue generated by selling of cortan commodity is given by function R(x)=80x-0.2x^ 2 , where he maximum reveremany should be manufactured to obtain this maximum units .Let's find out:
We have following function as . Let's differentiate this and equate it to zero to find value of x for which the function is maximum!
⇒
⇒
⇒
⇒
⇒
⇒
Now , Value of function at x=200 is :
⇒
⇒
⇒
Therefore , The maximum units is 200 and , Total revenue is $8,000
